Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, which has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

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

Front

Where is potential energy at its minimum?

Back

Potential energy is at its minimum when the object is at its lowest point in a gravitational field.

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 energy transform from potential to kinetic?

Back

Energy transforms from potential to kinetic when an object begins to move, converting stored energy into energy of motion.

Front

What is an example of potential energy?

Back

An example of potential energy is a rock held at the top of a hill, which has the potential to fall.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a car driving down the road.

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.
