Brainpop Potential Energy

What is potential energy?

• the energy an object has due to its position or condition

• the energy an object has due to its motion

• energy an object has due its chemical composition

• energy an object has due to its atomic strucure

When does an object have no kinetic energy?

• When it's at rest (not moving)

• when it's moving very slowly

• when the only force that's acting on it is gravity

• when it has no electrical charge

Which object has the most potential energy?

• a ball resting on the ground

• a ball being thrown at 100 miles per hour

• a ball on top of a refrigerator

• a ball resting on the edge of the top of a mountain

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

What do potential and kinetic energy have in common?

• they're both related to density

• neither of them are related to mass

• they're both related to volume

• they're both related to motion

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 gravity gives objects at low elevations the potential to fall much further.

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