Work , Power, and Energy

Front

What is the formula for work?

Back

W = Fd, where W is work, F is force, and d is distance.

Front

What is the formula for power?

Back

P = W / t, where P is power, W is work, and t is time.

Front

What would you solve for if given time and work?

Back

Power.

Front

If you push against a stationary object and it does not move, did you do work?

Back

No, work wasn't done.

Front

Who has greater power if both do the same work but one takes less time?

Back

The person who takes less time has greater power.

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 unit of work?

Back

The unit of work is the Joule (J).

Front

What is the relationship between work, power, and time?

Back

Power is the rate at which work is done, calculated as P = W / t.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, PE = mgh.
