Which is evidence that a bowling ball has more energy when it is moving faster than when it is moving slower?

• The bowling ball can knock over more pins when it is moving faster than when it is moving slower.

• The bowling ball will reach the pins in less time when it is moving faster than when it is moving slower.

• A bowling ball can knock over more pins than a soccer ball moving at the same speed.

• The bowling ball has a larger mass when it is moving faster than when it is moving slower.

There are 2 ramps with books standing at the bottom. One ramp is taller than the other. If you roll a ball down each ramp, which ball will hit the books harder?

• They will hit at the same time

• The shorter ramp will have the ball hit the books faster.

• The taller ramp will have the ball hit the books faster.

Which is not evidence of what happens during a roller coaster ride?

• As the cars go down the hill, the energy of motion increases.

• As the cars slow down at the end of the ride, energy of motion decreases.

• As the cars pull to the top of the first hill, the potential energy decreases

• As the cars pull to the top of the first hill, the potential energy increases.

How can the speed of a dropped ball be increased?

• Increase the height from which it is dropped to give it more potential energy

• roll it down a hill instead to increase the amount of friction

• decrease the height from which it is dropped to give it more potential energy

• drop a larger ball to increase the amount of friction
