1. If you do 10 joules of work to move an object 20 meters, what force do you apply?

200 newtons

2 newtons

1/2 newton

2. What distance is measured to determine the work when throwing a ball?

The height above the ground before you throw the ball

The distance from holding the ball until letting it go

The distance from when you let the ball go until it lands on the ground

3. How much work is done when a 2-pound brick is lifted 6 feet?

12 foot-pounds

12 newtons

No work is done

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
