Work and Power Flashcard

Front

What is Work in physics?

Back

Work is defined as the product of force and the distance over which it acts. It is calculated using the formula: Work = Force x Distance.

Front

What is the metric unit for Work?

Back

The metric unit for Work is Joules (J).

Front

What is Power in physics?

Back

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

Front

What is the metric unit for Power?

Back

The metric unit for Power is Watts (W).

Front

If a new forklift can do four times the amount of work in the same amount of time as an old forklift, how does their power compare?

Back

The new forklift is four times as powerful as the old forklift.

Front

What is the formula to calculate Work?

Back

Work = Force x Distance.

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

What is Force?

Back

Force is a push or pull acting upon an object.

Front

What is the metric unit for Force?

Back

The metric unit for Force is Newtons (N).

How do you calculate the net work done when multiple forces are acting on an object?

Back

Net Work = Net Force x Distance moved in the direction of the net force.
