Unit 5: Potential or Kinetic

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is kinetic energy?

Back

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

Front

Give an example of potential energy.

Back

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

Front

Give an example of kinetic energy.

Back

A moving car has kinetic energy due to its motion.

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of an object and its mass.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and the square of its velocity.

Front

How can potential energy be converted to kinetic energy?

Back

When an object falls, its potential energy is converted into kinetic energy as it gains speed.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height in a gravitational field.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
