8th Grade Potential and Kinetic Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What factors determine potential energy?

Back

Potential energy is determined by an object's height and mass.

Front

What happens to kinetic energy when an object's speed increases?

Back

The kinetic energy increases as the speed of the object increases.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does mass affect potential energy?

Back

The greater the mass of an object, the greater its potential energy when at a height.

Front

What type of energy does a stationary object have?

Back

A stationary object has potential energy, but no kinetic energy.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy.
