Discussion: Observation and experience suggest two behaviors when a stone is thrown along a water surface: 1 Ifthe angle between the path of the stone and the water surface is steep the stone may penetrate the water surface. Some momentum of the stone will be converted to momentum of the water in the resulting splash.
Then, because the stone is heavier than water it will sink. The splash will be smaller than if the stone penetrated the water surface. This will transfer less momentum to the water, causing less reduction in speed of the stone. The only drag force on the stone will be from friction on the water surface. The drag will be momentary, causing the stone to lose only a portion of its kinetic energy. Instead of sinking, the stone may skip off the surface and become airborne again.
With each skip the stone loses some forward speed. After several skips the stone loses enough forward speed to penetrate the surface and sink into the water. Observation suggests that the shape of the stone significantly affects skipping. Essentially spherical stones may be made to skip with considefable effort and skill from the thrower.
Flatter, more disc-shaped stones are more likely to skip, provided they are thrown with the flat surface s essentially parallel to the water surface; spin may be used to stabilize the stone in flight. By contrast, no stone can ever penetrate the pavement of a roadway.
Each collision between stone and roadway will be inelastic; friction between the road surface and stone will affect the motion of the stone only slightly. Regardless of the initial angle between the path of the stone and the surface of the roadway, the stone may bounce several times, then finally it will roll to a stop. Problem 1. Explain the mechanisms responsible for the temperature increase. Discussion: Two phenomena are responsible for the temperature increase: 1 friction between the pump piston and barrel and 2 temperature rise of the air as it is compressed in the pump barrel.
Friction between the pump piston and barrel converts mechanical energy force on the piston, moving through a distance into thermal energy as a result of friction.
Lubricating the piston helps to provide a good seal with the pump barrel and reduces friction and therefore force between the piston and barrel. The compression is not adiabatic because it occurs during a finite time interval. Heat is transferred from the warm compressed air in the pump barrel to the cooler surroundings. This raises the temperature of the barrel, making its outside surface warm or even hot! Find: a Density and speerhe gravity. Solution: Lateral!
