When considered together, the object and the mass constitute a closed system in which total momentum is conserved.

When the temperature and pressure in the core become sufficient to ignite helium fusion, a helium flash will occur if the core is largely supported by electron degeneracy pressure ( stars under 1. 4 solar mass ).

When Shaka's mother Nandi died for example, the monarch ordered a massive outpouring of grief including mass executions, forbidding the planting of crops or the use of milk, and the killing of all pregnant women and their husbands.

When in static equilibrium, the system is either at rest, or its center of mass moves at constant velocity.

When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system.

When released, the restoring force combined with the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth.

When the metric system was introduced in France in 1795, it included units for length, area, dry volume, liquid capacity, weight or mass, and even currency, but not for time.

When this effect is taken into account, typical gamma-ray bursts are observed to have a true energy release of about 10 < sup > 44 </ sup > J, or about 1 / 2000 of a Solar mass energy equivalent.

When all means of self-support are exhausted, the affected population begins to migrate in search of food or fall victim to outright mass starvation.

When massed Confederate artillery devastated a Union assault by Maj. Gen. Fitz John Porter's V Corps, Longstreet's wing of 25, 000 men in five divisions counterattacked in the largest, simultaneous mass assault of the war.

When the US markets collapsed in the Panic of 1819 – a result of global economic adjustments – the central bank came under withering criticism for its belated tight money policies – policies that exacerbated mass unemployment and plunging property values.

When Rosenfeld named them, the only known leptons were electrons and muons, which are in fact of small mass — the mass of an electron () and the mass of a muon ( with a value of ) are fractions of the mass of the " heavy " proton ().

When I say move, a guy moves ''!!

" When the tone poem moves into the blues, " our American friend ... has succumbed to a spasm of homesickness.

When the wind blows horizontally, it presses on and moves the ball ; because ping-pong balls are very lightweight, they move easily in light winds.

When rates move higher, the bond part of a convertible bond tends to move lower, but the call option part of a convertible bond moves higher ( and the aggregate tends to move lower ).

When the price of the stock the bond is convertible into moves higher, the price of the bond tends to rise.

When the particle moves, its velocity is

When a pilot moves the control column ( or sidestick ), a signal is sent to a computer ( analogous to moving a game controller ) the signal is sent through multiple wires ( channels ) to ensure that the signal reaches the computer.

When the listener moves slightly to the side, however, this phantom channel disappears or is greatly reduced.

When a river is in flood, it is at its most powerful, and moves the greatest amount of sediment.

When the hailstone moves into an area with a high concentration of water droplets, it captures the latter and acquires a translucent layer.

When the piston moves further down and the cylinder doesn't have anymore gases, fuel mixture starts to flow to the combustion chamber and the second process of fuel compression starts.

Operation: When the piston moves from bottom dead center ( BDC ) to top dead center ( TDC ) the fresh air and fuel mixture enters the crank chamber through the intake port.

When a key is depressed, it moves a magnet, which is detected by the solid-state sensor.

" When " Air steps " or " aerials " such as the Hip to Hip, Side Flip, and Over the Back ( the names describe the motion of the woman in the air ) began to appear in 1936, the old guard of dancers such as Leon James, Leroy Jones, and Shorty Snowden disapproved of the new moves.

When the Union of South Africa was founded in 1910 the colony was still controlled by the British and moves were made to transfer it to the Union.

When a body at these points is perturbed, it moves away from the point, but the factor opposite of that which is increased or decreased by the perturbation ( either gravity or angular momentum-induced speed ) will also increase or decrease, bending the object's path into a stable, kidney-bean-shaped orbit around the point ( as seen in the rotating frame of reference ).

When a charged particle moves through a magnetic field B, it feels a Lorentz force F given by the cross product:

" Actor Jack Nicholson once said, " When Marlon dies, everybody moves up one.

When the moon is closer to the earth, it moves faster ; when it is farther, it moves slower.

When León became the first city in Nicaragua to fall to the Sandinistas, he responded with aerial bombardment, famously ordering the air force to " bomb everything that moves until it stops moving.

When you bend backward the top ( base ) of the sacrum moves forward relative to the ilium ; when you bend forward the top moves back.

When the important action shifts to a new position in the frame, the operator moves the scanner to follow it, creating the effect of a " pan " shot.

When the temporal weapon fires on an object, it moves that object outside the space-time continuum, eliminating the object from causality not only in the present and the future, but also the past, changing history to a state where the object never existed.
