Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object has due to its mass and motion.

Front

What is potential energy?

Back

Potential energy is the stored energy that an object has due to its position or height.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)².

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What happens to kinetic energy when an object slows down?

Back

The kinetic energy decreases as the object's speed decreases.

Front

What happens to potential energy when an object is lifted higher?

Back

The potential energy increases as the object's height increases.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of energy transfer?

Back

When a soccer ball is kicked, kinetic energy is transferred from the foot to the ball.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.
