An object hanging in the air (not moving) is said to have

• kinetic energy

• potential energy

• elastic energy

• chemical energy

As you run down the hallway to get to class on time, you feel a breeze hitting your face. This is

• gravitational force

• tension force

• air drag force

• frictional force

If a rope is pulling on an object, a(n) _________ force is being applied

• air drag

• tension

• friction

• normal

• chemical

• kinetic

• potential

• elastic

The reason a ball bounces higher than a rock when they both hit the floor is, because

• the rock needs to be raised a little bit higher to bounce as high

• the rock has more gravitational force being applied than the ball

• the ball has less frictional force on it than the rock

• the ball has more elastic energy within it compared to the rock

The amount of energy within a closed system

• remains constant

• can be transferred within the system

• can always be accounted for

• all of the above
