What is potential energy?
The energy an object has due to its atomic structure.
The energy an object has due to its chemical composition.
The energy an object has due to its motion.
The energy an object has due to its position or condition.
What is kinetic energy?
The energy an object has due to its position or condition
The energy an object has due to its motion
The energy an object has due to its chemical composition
The energy an object has due to its atomic structure
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.
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 a cliff.
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.
They're both unrelated to size.
They're both related to volume.
They're both related to motion.
Which is the best synonym for potential energy?
Stored energy
Energy of motion
Energy due to gravity
Mechanical energy
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
All of the pictures are examples of what type of energy?
gravitational potential energy
elastic potential energy
chemical potential energy
kinetic potential energy
Gravitational potential energy depends on which two factors?
mass and height above the ground
distance and speed
speed and height above the ground
mass and speed
