Work and Power JM

Front

What is the rate at which work is done?

Back

Power

Front

What is the formula for work?

Back

Work = force x distance

Front

What does the law of conservation of energy state?

Back

The mechanical energy of a system neither increases nor decreases in any process; it stays constant and is conserved.

Front

If you push a cart with a force of 60 N for 2 m, how much work have you done?

Front

What is the unit of power?

Back

Watt (Joule per second)

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 the SI unit of work?

Back

Joule (J)

Front

How is power calculated?

Back

Power = Work / Time

Front

What is the relationship between work and energy?

Back

Work is a transfer of energy; when work is done, energy is transferred from one system to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².
