Work, Power, Simple Machines

Front

What is Work in physics?

Back

Work is done when a force causes an object to move. 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) x Distance (d) where Work is measured in joules.

Front

What is Power in physics?

Back

Power is the rate at which work is done or energy is transferred. It is measured in watts.

Front

What is the formula for calculating Power?

Back

Power (P) = Work (W) / Time (t) where Power is measured in watts.

Front

What is Mechanical Advantage (MA)?

Back

Mechanical Advantage is the ratio of the output force produced by a machine to the input force applied to it.

Front

How do you calculate Mechanical Advantage?

Back

Mechanical Advantage (MA) = Effort Length / Resistance Length.

Front

What are Simple Machines?

Back

Simple machines are devices that make work easier by allowing us to apply force in a more effective way. Examples include levers, pulleys, and inclined planes.

Front

What is an example of a lever?

Back

A crowbar is an example of a lever, which helps lift heavy objects with less effort.

Front

What units are used to measure Force?

Back

Force is measured in newtons (N).

Front

What units are used to measure Work?

Back

Work is measured in joules (J).
