Physics Work & 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 square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state. It can be converted into kinetic energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object as it is raised above the ground, calculated as the product of mass, gravitational acceleration, and height.

Front

What is Work in physics?

Back

Work is done when a force causes an object to move. It is calculated as the product of the force and the distance moved in the direction of the force.

Front

What is the formula for calculating Work?

Back

Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the relationship between Work and Energy?

Back

Work is a transfer of energy. When work is done on an object, energy is transferred to that object.

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

What is the difference between Kinetic and Potential Energy?

Back

Kinetic Energy is energy of motion, while Potential Energy is stored energy based on an object's position.
