Work energy power

Front

What does the Law of Conservation of Energy state?

Back

The total amount of energy in a closed system will always stay the same.

Front

What is the SI unit of work?

Back

Joules.

Front

What type of energy is the sum of kinetic energy (KE) and potential energy (PE)?

Back

Total mechanical energy.

Front

What must happen for work to be done when a force is exerted on an object?

Back

The object must move.

Front

What condition must be true for work to be done?

Back

Force acts in the same direction as the distance traveled.

Front

Define work in physics.

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How is work calculated?

Back

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

Front

What is power in the context of work and energy?

Back

Power is the rate at which work is done or energy is transferred.
