Phenomena that in classical mechanics are ascribed to the action of the force of gravity ( such as free-fall, orbital motion, and spacecraft trajectories ), correspond to inertial motion within a curved geometry of spacetime in general relativity ; there is no gravitational force deflecting objects from their natural, straight paths.

At 220 feet, Dar's stunt from Atlanta's Westin Peachtree Plaza hotel in Sharky's Machine still holds up as the highest free-fall ( no wires ) stunt to ever be performed from a building for a commercially-released film.

* B28EX — ( EXternal ), streamlined external-carriage version for free-fall delivery ( no parachute )

The free-fall time is the characteristic time that would take a body to collapse under its own gravitational attraction, if no other forces existed to oppose the collapse.

For example, astronauts in a space shuttle may experience space sickness when their vestibular systems are indicating free-fall and their visual sensory systems are indicating no movement.

As can be shown using simple thought experiments following the free-fall trajectories of different test particles, the result of transporting spacetime vectors that can denote a particle's velocity ( time-like vectors ) will vary with the particle's trajectory ; mathematically speaking, the Newtonian connection is not integrable.

Passive gravitational mass is determined by dividing an object ’ s weight by its free-fall acceleration.

Also used in PCs to park the hard disk head when free-fall is detected, to prevent damage and data loss.

In particular, Alcubierre has shown that even when the ship is accelerating, it travels on a free-fall geodesic.

It is also known as the universal gravitational constant, Newton's constant, and colloquially as Big G. It should not be confused with " little g " ( g ), which is the local gravitational field ( equivalent to the free-fall acceleration ), especially that at the Earth's surface.

A small stabilizer chute deployed successfully, and Kittinger fell for 4 minutes and 36 seconds, also setting a still-standing world record for the longest parachute free-fall, if falling with a stabilizer chute is counted as free-fall.

This assumption is a simplification as free-fall only truly applies to the planetary center, but will suffice for this derivation.

This classic comic strip " flop take " is accompanied by a free-fall onomatopoeic sound ( usually ¡ Plop !).

To impart the most kinetic energy to a spacecraft whose free-fall velocity varies with time, the burn must occur when the probe is moving fastest, which usually occurs at periapsis ( the point of closest approach ).

The g-force associated with an object is its acceleration relative to free-fall.

A speed slide is a type of body slide where riders are sent down steep, free-fall plunges to the ground.

Based on wind resistance, for example, the terminal velocity of a skydiver in a belly-to-earth ( i. e.: face down ) free-fall position is about 195 km / h ( 122 mph or 54 m / s ).

However its true " free-fall " is only.

; MegaZip Adventure Park: located at the top of Mount Imbiah, MegaZip Adventure Park is Singapore's first adventure park with one of the longest and steepest zip wires in Asia, a 12m high ropes course, a free-fall parachute simulator and a challenging climbing wall.

Another way of stating this is that by measuring weight, an accelerometer measures the acceleration of the free-fall reference frame ( inertial reference frame ) relative to itself ( the accelerometer ).

Another example is free-fall at a sufficiently high altitude that atmospheric effects can be neglected.

Freescale MMA7341L, a 3-axis accelerometer with analog output that has adjustable sensitivity (± 3 g or ± 11 g ), and a 0g-detect digital output that signals when the board is in free-fall (± 3 g sensitivity setting only ).

Formation skydiving is the art of building formations in free-fall with multiple people gripping each other's limbs or specially built " grippers " on their jumpsuits.

Gravitational field can be measured by allowing a small ‘ test object ’ to freely fall and measuring its free-fall acceleration.

But since the infalling part of the orbit is symmetric to the hypothetical outgoing portion of the orbit, we can simply divide the period of the full orbit by two to attain the free-fall time ( the time along the infalling portion of the orbit ).

This may take the form of a manually operated crank or pump, or a mechanical free-fall mechanism which disengages the uplocks and allows the landing gear to fall due to gravity.

This may take the form of a manually operated crank or pump, or a mechanical free-fall mechanism which disengages the uplocks and allows the landing gear to fall due to gravity.

The center of mass of the diver follows a parabolic path in free-fall under the influence of gravity ( ignoring the effects of air resistance, which are negligible at the speeds involved ).

Reversible pendulums remained the standard method used for absolute gravity measurements until they were superseded by free-fall gravimeters in the 1950s.

A free-fall or gravity drop system uses gravity to deploy the landing gear into the down and locked position.

Kittinger set unbeaten () world records for: high-altitude jump ; free-fall by falling 16. 0 miles ( 25. 7 kilometers ) before opening his parachute ; and the fastest speed attained by a human being without mechanical or chemical assistance, about 982 k. p. h ( 614 m. p. h .).

* 1919 – Leslie Irvin of the United States makes the first successful voluntary free-fall parachute jump using a new kind of self-contained parachute.

Over the target the engine would cut out and the missile would free-fall before detonating its warhead as an air burst.

For example, an object in free-fall near the Moon will experience less gravitational field, and hence accelerate slower than the same object would if it were in free-fall near the Earth.

Without Soviet aid, North Korea's economy went into a free-fall.

At launch the A-4 propelled itself for up to 65 seconds on its own power, and a program motor controlled the pitch to the specified angle at engine shutdown, from which the rocket continued on a ballistic free-fall trajectory.

In 1971 while he was location scouting for Aguirre, the Wrath of God in Peru he narrowly avoided taking LANSA Flight 508 which later disintegrated after being struck by lightning with one miraculous free-fall survivor.

According to the Guinness book of records, Eugene Andreev ( USSR ) holds the official FAI record for the longest free-fall parachute jump ( without drogue chute ) after falling for 80, 380 ft ( 24, 500 m ) from an altitude of 83, 523 ft ( 25, 457 m ) near the city of Saratov, Russia on 1 November 1962.

If he condemns the recent or the present, he condemns the past with no less force.

The fact that he has cast over those materials the light of a skeptical mind does not make him any the less Southern, I rather think, for the South has been no more solid than other regions except in the political and related areas where patronage and force and intimidation and fear may produce a surface uniformity.

In order to prevent this, Washington hastened to dispatch several units to reinforce the fort, including a force under the Marquis De Lafayette containing some 160 of Morgan's riflemen, all who were fit for duty at this time, the rest having no shoes.

Apparently no serious disorders resulted from the celebration, and within a few days, Morgan joined the force of Lafayette who now had command of some 2,000 men at Barren Hill, not far above Philadelphia on the Schuylkill.

There is no explanation of terms nor a qualification that most such revolts have been dealt with by force -- only a bald dogmatism that they must, because of some undefined compulsion, be so repelled.

Ezra Stiles Gannett, an honorable representative of the sanhedrin, addressed himself frankly to the issue in 1845, insisting that Parker should not be persecuted or calumniated and that in this republic no power to restrain him by force could exist.

But one does not have to affirm the existence of an evil order irredeemable in that sense, or a static order in which no changes will take place in time, to be able truthfully to affirm the following fact: there has never been justitia imprinted in social institutions and social relationships except in the context of some pax-ordo preserved by clothed or naked force.

Snow or no, the fans were present in force at the Metropolitan Opera last night for a performance of the Ponchielli work.

Where territory is occupied in the course of hostilities by an enemy's force, even if the annexation of the occupied country is proclaimed by the enemy, there can be no change of allegiance during the progress of hostilities on the part of a citizen of the occupied country ( R v Vermaak ( 1900 ) 21 NLR 204 ( South Africa )).

A natural-born subject owes allegiance wherever they may be, so that where territory is occupied in the course of hostilities by an enemy's force, even if the annexation of the occupied country is proclaimed by the enemy, there can be no change of allegiance during the progress of hostilities on the part of a citizen of the occupied country ( R v Vermaak ( 1900 ) 21 NLR 204 ( South Africa )).

Paneloux is at pains to emphasize that God did not will the calamity: " He looked on the evil-doing in the town with compassion ; only when there was no other remedy did He turn His face away, in order to force people to face the truth about their life " In Paneloux's view, even the terrible suffering caused by the plague works ultimately for good.

Furthermore, Linda & Morris Tannehill argue that no coercive monopoly of force can arise on a truly free market and that a government's citizenry can ’ t desert them in favor of a competent protection and defense agency.

The first Abstract Expressionists were considered madmen to give up their brushes and rely on the sheer force of energy to leave an image, but then the import of atomic bombs, all atomic energy, became realized, and art found no better way of expressing its power.

* Article 4 – The treaty does not recognize, dispute, nor establish territorial sovereignty claims ; no new claims shall be asserted while the treaty is in force ;

One method of building a mooring is to use three or more conventional anchors laid out with short lengths of chain attached to a swivel, so no matter which direction the vessel moves one or more anchors will be aligned to resist the force.

::" For here is the chief and most confounding objection to excessive skepticism, that no durable good can ever result from it ; while it remains in its full force and vigor.

The system should not force him to lie under oath, nor to go to trial with no promise of the ultimate outcome concerning guilt or punishment.

Though the service is no longer offered, these laws remain in force.

If the net force on some body is directed always toward some fixed point, the center, then there is no torque on the body with respect to the center, and so the angular momentum of the body about the center is constant.

In 1999 after a creation of the Ministry of Defence ( MoD ), the Aeronautic Ministry changed its designation to Aeronautic Command, but no big changes happened to the air force structure, it kept almost the same organization it had before.
