Question 5 (Multiple Choice Worth 2 points)

When describing how power and work are similar you would want to mention that

you must know time to determine both work and power.

you must know force in order determine both work and power.

you must know energy in order to determine both work and power.

you must know velocity to determine both work and power.

Question 7 (Multiple Choice Worth 2 points)

The same force is applied to two skateboards. One rolls across the room and the other moves a few feet and comes to a stop. Where was there more work done?

The skateboard that traveled the shorter distance shows more work because there was more resistance.

The skateboard that traveled the longer distance shows more work because it was lighter.

The skateboard that traveled further shows more work because the distance was greater.

The skateboard that traveled the shorter distance shows more work because the force was greater.

Question 8 (Multiple Choice Worth 2 points)

If you are given force and time, you can determine power if you can know

watts.

energy.

joules.

distance.

Question 9 (Multiple Choice Worth 2 points)

If you were trying to describe the difference between power and work you could say:

To find power we need to know force and velocity; to find work we need to know force and distance.

To find power we need to know energy and distance; to find work we need to know energy and time.

To find power we need to know distance and time; to find work we need to know velocity and distance.

To find power we need to know energy and velocity; to find work we need to know distance and force.
