**The kinetic energy of an object is increased 8 times as a**result of: • Increasing the mass 4 times • Increasing the speed 4 times • Increasing both the mass and the speed 2 times • Increasing the speed 8 times • Applying a force which is 8 times greater**When an object is dropped from a tower, what is the effect**of the air resistance? • Increases the objects kinetic energy • Increases the objects potential energy • Does positive work on the object • Decreases the objects mechanical energy • None of the above is correct**The kinetic energy of an object is increased by a factor of**27 by: • Decreasing the mass 3 times and increasing the speed 3 times • Increasing the mass 3 times and increasing the speed 3 times • Increasing the speed 27 times and keeping the mass constant • Decreasing the mass 27 times and increasing the speed 9 times • None of the above is correct**Two blocks (heavy and light) are released from the top of a**building. The light falls straight down and the heavy slides down a ramp. If all friction is ignored, which one is moving faster when they reach the bottom? • heavy • light • both move with the same speed at the bottom • depends on the slide shape • insufficient information given
