Work and Power

Front

What is 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 Power in physics?

Back

Power is the rate at which work is done or energy is transferred. It is calculated as Power = Work / Time.

Front

How do you calculate Work?

Back

Work is calculated using the formula: Work = Force x Distance.

Front

What is the unit of Work?

Back

The unit of Work is the Joule (J).

Front

What is the unit of Power?

Back

The unit of Power is the Watt (W).

Front

If 90 joules of work is done in 30 seconds, what is the power generated?

Back

3 watts.

Front

What is the relationship between Work, Power, and Time?

Back

Power is the amount of work done per unit of time.

Front

What is Force?

Back

Force is a push or pull on an object that can cause it to accelerate. It is measured in Newtons (N).

Front

What happens when you lift an object?

Back

When you lift an object, you do work against the force of gravity.

Front

Is work done when carrying an object at a constant height?

Back

No, work is only done when the object moves in the direction of the force applied.
