Energy Test Review

Front

What happens to a skater's potential energy as they travel down a ramp?

Back

The skater loses potential energy as they travel down the ramp.

Front

What type of energy does the food you eat provide your body?

Back

Chemical energy.

Front

What is the energy stored between atoms, ions, and molecules called?

Back

Chemical energy.

Front

If Machine A and Machine B do the same amount of work, but Machine A does it faster, which machine has more power?

Back

Machine A has more power.

Front

When does a skater have the most kinetic energy?

Back

At the bottom of the ramp.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or arrangement.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How is power defined in physics?

Back

Power is the rate at which work is done or energy is transferred.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.
