Kinetic and Potential 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

What factors affect potential energy?

Back

Potential energy depends on two main factors: mass and height. The higher an object is and the more mass it has, the greater its potential energy.

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 calculating 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 calculating 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

Give an example of kinetic energy.

Back

A car moving at 60 km/h is an example of kinetic energy.

Front

Give an example of potential energy.

Back

A stretched rubber band is an example of potential energy.

Front

How does speed affect kinetic energy?

Back

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

Front

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest points of the swing, while kinetic energy is highest at the lowest point.
