kinetic energy
mechanical energy
The amount of kinetic energy in a moving object depends on its _____ and _____.
height
force
speed
mass
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
Which is the best synonym for potential energy?
Stored energy
Energy of motion
Energy due to gravity
Mechanical energy

B
C
D
What do potential and kinetic energy have in common?
They're both related to density.
They're both unrelated to size.
They're both related to volume.
They're both related to motion.
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.
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.
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 a cliff.
When does an object have no kinetic energy?
When it's at rest.
When it's moving very slowly.
When the only force that's acting on it is gravity.
