Collision Energy

To play croquet, you hit a ball through metal hoops with a wooden mallet. If your ball touches another player’s, you can “send” the other player’s ball off course. What will happen when the player strikes the ball with the mallet?

• The ball that is hit with the mallet will compress and then stretch back to move the other ball.

• Kinetic energy will travel through the ball that is hit with the mallet, and the other ball will move.

• Sound energy will travel through the ball that is hit with the mallet, but neither ball will move.

• Kinetic energy is transformed into sound energy, but the balls will not move.

Which conclusion is best supported by the evidence in the table?

• The baseball compressed and stretched the most.

• The golf ball has the greatest mass.

• The table tennis ball compressed and stretched the least.

• The basketball takes longer to bounce than the other balls.

Look at the picture. What three things take place when the bat makes contact with the ball?

• Energy transfer causes a change in motion.

• Chemical energy is transformed into kinetic energy and heat.

• Some of the ball's kinetic energy is transformed into thermal energy.

• Sound energy is transferred to the surroundings.

The picture shows a snowball hitting a brick wall. Which two statements describe the energy involved when the snowball and wall collide?

• The change in the snowball's speed is evidence for a change in energy.

• There is no energy transfer because the snowball falls apart.

• The kinetic energy of the snowball does not transfer to the wall.

• The kinetic energy of the snowball is transferred to the surroundings and to the chunks of snow that spread out.

In Newton’s Cradle, why do the CENTER spheres barely move?

• The center spheres are to heavy

• The center spehre don't have enough energy

• Most of the kinetic energy is transferred through the center spheres to the end.

• There is no reason

Suppose you went bowling WITHOUT a bowling ball. You had to use a large plastic ball (like the ones in a ball pit). How would the speed and motion of a large plastic ball be different than using a bowling ball?

• The large plastic ball would need less energy to knock the pins down.

• The large plastic ball is too light to have any energy.

• The large plastic ball would need more speed and energy to knock down the pins.

• The large plastic ball would need less speed to knock down the pins.
