Work, Power, & Simple Machines Test

Front

What is effort (input) force?

Back

The force required by a machine in order to accomplish work (the force you put on the machine).

Front

What is resistance (output) force?

Back

The force which an effort force must overcome in order to do work on an object via a simple machine.

Front

What is a lever?

Back

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

Front

What is power in physics?

Back

The rate at which work is done or energy is transferred, measured in watts (W).

Front

How do you calculate power?

Back

Power = Work done / Time taken.

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force, calculated as Work = Force x Distance.

Front

What is a simple machine?

Back

A device that makes work easier by allowing us to push or pull over increased distances.

Front

What is an inclined plane?

Back

A flat surface that is tilted at an angle to help lift objects with less effort.

Front

What is a pulley?

Back

A simple machine that uses a wheel and a rope to lift or lower objects.

Front

What is a wheel and axle?

Back

A simple machine consisting of a larger wheel attached to a smaller axle, allowing for easier movement.
