Work, Power, and Simple Machines remediation

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 the unit of work?

Back

The unit used to measure work is the Joule (J).

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

What is the unit of power?

Back

The unit used to measure power is the Watt (W).

Front

What is a simple machine?

Back

A simple machine is a device that makes work easier by allowing us to apply force in a more efficient way.

Front

What are the six types of simple machines?

Back

The six types of simple machines are lever, wedge, screw, pulley, inclined plane, and wheel and axle.

Front

What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum.

Front

What are the three classes of levers?

Back

The three classes of levers are: 1st Class (fulcrum in the middle), 2nd Class (load in the middle), and 3rd Class (effort in the middle).

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split or cut objects, consisting of two inclined planes.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help lift objects with less effort.
