Review: Kinetic & Potential Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is the energy that has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. It is the energy that an object possesses due to its movement.

Front

What does the conservation of energy principle state?

Back

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

Front

How does height affect potential energy?

Back

Potential energy increases with height. The higher an object is positioned, the more potential energy it has due to gravitational force.

Front

What is the formula for 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 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.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, demonstrating the conservation of energy.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height above the ground.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy is proportional to the square of the speed. If the speed doubles, the kinetic energy increases by a factor of four.
