Media Image

The energy of a moving object due to its motion is

Potential Energy

Kinetic Energy

Work

Motion Energy

Answer explanation

Kinetic energy is the energy of an object due to its motion. The faster it's going, the more kinetic energy it has!

What do we call energy that is stored in an object's position?

Thermal

Kinetic

Nuclear

Potential

Answer explanation

Potential energy is energy that is stored. It can be gravitational potential energy (possessed by objects that are up high off the ground) and elastic potential energy (stored in objects that are stretched out)

An object's gravitational potential energy depends on what?

Its mass and its speed

The chemical bonds between its atoms

Its height from the Earth and its mass

Its temperature

Answer explanation

Media Image

The gravitational potential energy of an object is decided by two factors: its height off the ground and its mass.

In the image above, Object C has the greatest gravitational potential energy, because it has a greater mass than Object B (which is at its same height), and it is at a greater height than Object A, which has the same mass.

Compared to a slow-moving object, a faster-moving object has ___________

more kinetic energy

less kinetic energy

the same amount of kinetic energy

zero kinetic energy

Answer explanation

If two objects have the same mass, the one that's moving faster will have a greater kinetic energy.

Media Image

A rock balances on the edge of a cliff, about to fall. What kind of energy does it have?

Gravitational potential energy

Kinetic energy

All of the above

None of the above

Answer explanation

The rock has gravitational potential energy, because it is at a height above the ground, ready to fall.

It does not have kinetic energy, because it is not currently moving.

Media Image

A grocery cart rolls across a flat parking lot. What kind of energy best describes the energy of its wheels?

Gravitational potential energy

Kinetic energy

Elastic potential energy

None of the above

Answer explanation

The grocery cart has kinetic energy because it is moving. It does not have gravitational potential energy because it is not off the ground.
