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 its velocity.

Front

What is Potential Energy?

Back

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

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) × gravity (g) × height (h) where g is approximately 9.8 m/s² on Earth.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is 9.8 m/s².

Front

What happens to Potential Energy as an object is lifted higher?

Back

As an object is lifted higher, its Potential Energy increases because it has more stored energy due to its height.

Front

What is the relationship between Kinetic Energy and speed?

Back

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

Front

What is Work in physics?

Back

Work is done when a force causes an object to move. It is calculated as Work = force × distance.

Front

How do you calculate speed?

Back

Speed is calculated by dividing distance by time: Speed = Distance / Time.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).

Front

What is the difference between Kinetic and Potential Energy?

Back

Kinetic Energy is energy of motion, while Potential Energy is stored energy based on position.
