Potential vs Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is the energy that 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 the square of its velocity.

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h). For example, PE = mgh.

Front

What is the formula for Kinetic Energy?

Back

Kinetic Energy (KE) = 0.5 × mass (m) × velocity (v)².

Front

If a car has a mass of 1,000 kg and is at a height of 366 m, what is its Potential Energy?

Back

PE = 1,000 kg × 9.8 m/s² × 366 m = 3,588,000 J.

Front

What type of energy does food contain?

Back

Food contains Potential Energy.

Front

What happens to Kinetic Energy when the speed of an object doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four (since KE is proportional to the square of the velocity).

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has, as it is directly proportional to height.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases.
