Work Energy Power 1

Front

What is the definition of work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is the formula for calculating work?

Back

Work = Force x Distance (W = F x d)

Front

What unit is work measured in?

Back

Work is measured in joules (J).

Front

If no movement occurs, what is the work done on an object?

Back

If there is no movement, the work done is zero.

Front

What is the relationship between work and energy?

Back

Work is a transfer of energy. When work is done on an object, energy is transferred to that object.

Front

How much work is done when lifting a 300 N weight 1.5 m?

Back

900 J (Work = Force x Distance = 300 N x 1.5 m).

Front

True or False: Work can be done if the object does not move.

Back

False.

Front

What is power in relation to work?

Back

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

Front

What is the unit of power?

Back

Power is measured in watts (W), where 1 W = 1 J/s.

Front

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

Back

120 J (Work = Force x Distance = 60 N x 2 m).
