Potential Energy and Force

When does a yo-yo have the most potential energy?

• When it's at its highest point.

• When it's at its lowest point.

• When it's moving between its highest and lowest points.

• When it's moving at its top speed.

When is potential energy transformed into kinetic energy?

• When an object at rest is lifted to a higher elevation.

• When an object at rest remains at rest.

• When an object at rest is put into motion.

• When an object in motion is stopped and put at rest.

Why do objects at high elevations have more potential energy than objects at low elevations?

• Because the thinner air at higher elevations means objects have a greater potential to move very fast

• Because objects at high elevations are closer to the sun, which is the source of all energy on earth

• Because objects at high elevations tend to move slower than objects at low elevations

• Because gravity gives objects at high elevations the potential to fall much further
