Anything that has mass and volume.

The movement of an object some distance.

The conversion of weight into mass.

Which of the following is the best definition for energy?

2/7

Topical

A bike resting at the top of a hill would be an example of what type of energy?

3/7

next!

This statement is never true

This statement is true for all different types of energy

This statement is true for thermal and mechanical, but not elastic

This statement is false, except in the case of mechanical energy

Identify when the following statement is true: different types of energy can be categorized as either kinetic or potential.

4/7

next!

the weight of an object

the velocity of the object only

the mass of the object only

the mass of the object and the velocity of the object squared

To which of the following variables is kinetic energy proportional?

5/7

next!

A bottle of sugar sitting on the counter top

A bike rolling downhill

A car traveling at a constant speed

An elephant moving at 10 m.p.h.

Which of the following is an example of potential energy and not kinetic energy?

6/7

next!

Just past the top of the swing on the way back down

At the top of the swing

Mid way between the bottom and the top of the swing

just past the bottom of the swing on the way up

Consider a ball at the end of a string. If the ball is swinging back and forth, at what point in the swing would the ball have the most potential energy?
