Question
5. How can a hockey puck explain the transfer of kinetic energy? **Select all that apply.**
a
Kinetic energy is lost when it transfers between materials.
b
Energy transfers from materials through touch.
c
Kinetic energy can move from one item to another.
d
Kinetic energy transfers through air when materials are close.
6. Which best describes the law of conservation of energy?
a
Energy is always transferred from the system with the most energy to that with the least.
b
Energy can be created and destroyed in science labs.
c
Energy cannot be created or destroyed; it can only change form.
d
Energy exists in these forms: mechanical, chemical, thermal, electromagnetic, and nuclear.
7. In a game of pool, when the cue ball (white ball) is stuck, it collides with the solid blue #2 ball, transferring all of its kinetic energy. What will happen after the collision?
a
The Blue Solid #2 ball will come to a stop, just like the white cue ball.
b
The Blue Solid #2 ball will move away at half the speed because the kinetic energy is divided between the two balls.
c
The Blue Solid #2 ball will move away at the same speed because it has the same mass.
d
The Blue Solid #2 ball will move away at half the speed because the kinetic energy is divided between the two balls.

Here are the answers to your questions:
**5. How can a hockey puck explain the transfer of kinetic energy? (Select all that apply)**
- **c** Kinetic energy can move from one item to another.
- **d** Kinetic energy transfers through air when materials are close.
**6. Which best describes the law of conservation of energy?**
- **c** Energy cannot be created or destroyed; it can only change form.
**7. In a game of pool, when the cue ball (white ball) is stuck, it collides with the solid blue #2 ball, transferring all of its kinetic energy. What will happen after the collision?**
- **a** The Blue Solid #2 ball will come to a stop, just like the white cue ball.
(Note: The answer to question 7 may vary based on specific details about the masses of the balls and the energy transfer described, but if all kinetic energy is transferred and if they have the same mass, the cue ball would come to rest, and the Blue Solid #2 ball would move away with the original speed of the cue ball.)
