When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat.

When the blade of an ice skate passes over the ice, the ice undergoes two kinds of changes in its physical state and a change in temperature due to kinetic friction and the heat of melting.

When a body rotates while subject to tidal forces, internal friction results in the gradual dissipation of its rotational kinetic energy as heat.

When friction ridges come into contact with a surface that will take a print, material that is on the friction ridges such as perspiration, oil, grease, ink or blood, will be transferred to the surface.

When friction ridge skin is not available from military personnel's remains, DNA and dental records are used to confirm identity.

When the two surfaces come in contact during motion i. e. rub against each other, friction, wear and lubrication effects are very important to analyze in order to determine the performance of the material.

When the war ended a number of groups took up development of low friction water vessels including hydrofoil and water effects.

When flow is turbulent, particles exhibit additional transverse motion which enhances the rate of energy and momentum exchange between them thus increasing the heat transfer and the friction coefficient.

When on a clear and calm night, a radiation inversion is formed near the ground, the friction does not affect wind above the top of the inversion layer.

When the shoe slides over the outside of the hose, it creates friction and heat, which shortens hose life.

When a fluid is in solid body rotation it is the lowest state of energy that is available, because in a state of solid body rotation there is no friction to dissipate any of the energy.

When the soil is so soft that even friction piles will not support the building load, the final option is the use of a floating foundation, making the building like a boat that obeys Archimedes ’ principle — it is buoyed up by the weight of the earth displaced in creating the foundation.

When Beckett and Miller set off, friction immediately occurs between them, based in part on Beckett's insistence on deviating from the mission plan that Miller was given, but mostly on the fact that Miller ( though nominally in command ) has no experience or aptitude for jungle operations.

When the traction control computer ( often incorporated into another control unit, like the anti-lock braking system module ) detects one or more driven wheels spinning significantly faster than another, it invokes the ABS electronic control unit to apply brake friction to wheels spinning with lessened traction.

When the two graphite surfaces are in registry ( every 60 degrees ), the friction force is high.

When the two surfaces are rotated out of registry, the friction is largely reduced.

When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

When synchronization occurs, friction on the blocker ring is relieved and it twists slightly, bringing into alignment certain grooves and notches that allow further passage of the selector which brings the teeth together.

When the Revolution broke out, he, along with Jefferson and Jay, abandoned his career at the bar, with considerable financial sacrifice.

When the front knee is straight and locked, allow it to bend again until you feel the bar come lightly into contact with the sides of the Power Stands.

He recorded a number of tracks with the Dapps, a white Cincinnati bar band, including the hit " I Can't Stand Myself ( When You Touch Me )".

“ When the defense of laches is clear on the face of the complaint, and where it is clear that the plaintiff can prove no set of facts to avoid the insuperable bar, a court may consider the defense on a motion to dismiss .” Solow v. Nine West Group, 2001 WL 736794, * 3 ( S. D. N. Y.

When the first pubs were built, the main room was the public room with a large serving bar copied from the gin houses, the idea being to serve the maximum number of people in the shortest possible time.

When demonstrators broke through the windows — which had been covered by plywood by the bar owners to deter the police from raiding the bar — the police inside unholstered their pistols.

When the bar closed, he found that his entire rig — horse, buggy, and samples — had been stolen.

When asked about the subject, Daley said " I flunked the bar exam twice.

When gymnasts compete on the horizontal bar they are often required by the Code of Points to use specific grips.

When the bar and resonator are properly in tune with each other, the vibrating air beneath the bar travels down the resonator and is reflected off the closure at the bottom, then returns back to the top and is reflected back by the bar, over and over, creating a much stronger standing wave and amplifying the fundamental frequency.

When the second mallet strikes the bar the first mallet is removed.

When a " classic " application is in the foreground, the menu bar at the top of the screen changes to look like the older Mac OS system menu.

When the bar becomes motionless on the chest, the referee gives a press command.
