Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with the height of an object above the ground.

Front

Which has more kinetic energy: a moving car or a parked car?

Back

A moving car has more kinetic energy because it is in motion.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has due to the gravitational force acting on it.

Front

What is an example of energy transformation?

Back

When a roller coaster goes down a hill, potential energy is transformed into kinetic energy.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What is an example of an object with potential energy?

Back

A book on a shelf has potential energy because of its height above the ground.

Front

What happens to energy when a ball is thrown up?

Back

As the ball rises, kinetic energy is converted to potential energy until it reaches its highest point.
