Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state, commonly calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How do you calculate Kinetic Energy?

Back

Kinetic Energy (KE) is calculated using the formula KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

How do you calculate Potential Energy?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.81 m/s²), and h is the height above the ground.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

At which point in a pendulum's swing is Kinetic Energy highest?

Back

Kinetic Energy is highest at the lowest point of the swing.

Front

At which point in a pendulum's swing is Potential Energy highest?

Back

Potential Energy is highest at the highest points of the swing.

Front

What happens to Kinetic Energy as an object slows down?

Back

As an object slows down, its Kinetic Energy decreases.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.

If a car has a mass of 2600 kg and is moving at 25 m/s, what is its Kinetic Energy?

Back

The Kinetic Energy is 812,500 J.
