Potential and Kinetic Energy

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 the speed at which it is moving.

Front

What is Potential Energy?

Back

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

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has. Kinetic energy increases with the square of the speed.

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 speed.

Front

What is the formula for Potential Energy?

Back

The formula for 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, assuming no energy is lost to air resistance.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has potential energy due to its position and the force applied to compress it.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy due to its motion.

Front

At what point in a pendulum's swing is potential energy highest?

Back

Potential energy is highest at the highest points of the swing, where the pendulum momentarily stops before changing direction.

Front

What are the two factors that affect Kinetic Energy?

Back

The two factors that affect kinetic energy are mass and speed.
