Work and Power

Front

What is the definition of work in physics?

Back

Work is defined as the product of the force applied to an object and the distance over which that force is applied, in the direction of the force.

Front

What is the formula for calculating work?

Back

Work = Force x Distance

Front

What unit is work measured in?

Back

Work is measured in Joules (J).

Front

What is the relationship between force, distance, and work?

Back

Work is done when a force causes an object to move a certain distance in the direction of the force.

Front

True or False: Work can be done if there is no movement of the object.

Back

False. If there is no movement, no work is done.

Front

What happens to the work done if the distance is zero?

Back

If the distance is zero, the work done is also zero, regardless of the force applied.

Front

If a force of 10 N moves an object 5 m, how much work is done?

Back

Work = 10 N x 5 m = 50 J.

Front

What is power in relation to work?

Back

Power is the rate at which work is done, measured in Watts (W).

Front

How do you calculate power?

Back

Power = Work / Time.

Front

What is the unit of power?

Back

Power is measured in Watts (W), where 1 Watt = 1 Joule/second.
