Front

What happens to the kinetic energy of an object as its speed increases?

Back

The kinetic energy increases.

Front

What is the term for the process of moving energy from one place to another?

Back

Energy transfer.

Front

What types of energy does a wind-up toy possess when it is wound up and moving?

Back

It has both kinetic and potential energy.

Front

What does the law of conservation of energy state?

Back

Energy cannot be created nor destroyed, only transformed from one form to another.

Front

What type of energy does a ball rolling down a hill have?

Back

Kinetic energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Define potential energy.

Back

Potential energy is the stored energy of an object due to its position or state.

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 an example of energy conversion?

Back

A battery converting chemical energy into electrical energy.

Front

How does height affect potential energy?

Back

Potential energy increases with height, as it is directly proportional to the height of an object above a reference point.
