Energy, Work, and Power

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

How is work calculated?

Back

Work (W) = Force (F) x Distance (d) in the direction of the force.

Front

What is the unit of work?

Back

The unit of work is the Joule (J). 1 Joule is equal to 1 Newton meter.

Front

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred. It measures how quickly work is performed.

Front

How is power calculated?

Back

Power (P) = Work (W) / Time (t).

Front

What is the unit of power?

Back

The unit of power is the Watt (W). 1 Watt is equal to 1 Joule per second.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as mass (m) x gravity (g) x height (h).

Front

How is gravitational potential energy calculated?

Back

Potential Energy (PE) = mass (m) x gravity (g) x height (h).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 x mass (m) x velocity (v)².

Front

How is kinetic energy calculated?

Back

Kinetic Energy (KE) = 1/2 x mass (m) x velocity (v)².
