Potential and Kinetic Energy

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 be converted into kinetic energy.

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.

Where is potential energy maximum on a roller coaster?

Back

At the top of a big hill.

Front

Where is kinetic energy maximum on a roller coaster?

Back

At the bottom of a big hill.

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 formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mass (m) * gravity (g) * height (h).

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has, because potential energy is directly proportional to height.

Front

How does speed affect kinetic energy?

Back

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

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position.
