Work

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 the product of the force and the distance moved in the direction of the force.

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d) Where work is measured in Joules, force in Newtons, and distance in meters.

Front

What is the unit of measurement for work?

Back

Joules (J) is the unit of measurement for work.

Front

True or False: For work to be done on an object, the direction of the force and the direction of the movement must be the same.

Back

True

Front

If a force is applied but there is no movement, is work done?

Back

No, if there is no movement, then no work is done.

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 a force of 10 N moves an object 5 m?

Back

Work = Force × Distance = 10 N × 5 m = 50 Joules.

Front

If 500 J of work is done using a force of 50 N, how far does the object move?

Back

Distance = Work / Force = 500 J / 50 N = 10 m.

Front

What happens to the work done if the distance is doubled while applying the same force?

Back

The work done is also doubled, as work is directly proportional to distance.

Front

What is the effect of angle on work done?

Back

If the angle between the force and the direction of movement is not zero, only the component of the force in the direction of movement does work.
