Front

What is the formula for calculating work?

Back

Work = Force × Distance (W = F × d)

Front

Front

What is power in the context of work?

Back

Power is the rate at which work is done, calculated as Power = Work / Time.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy.

Front

What is an example of a non-contact force?

Back

Magnetic force.

Front

What is the difference between work and power?

Back

Work is the total energy transferred, while power is the rate of doing work.

If 300 J of work is done in 15 seconds, what is the power?

Back

20 W

Front

What is the significance of the direction of force in work?

Back

Only the component of force in the direction of motion does work.
