Simple Machines

Front

What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force, making work easier.

Front

Name the six types of simple machines.

Back

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

Front

What is the purpose of a pulley?

Back

A pulley is used to lift heavy objects by changing the direction of the force applied.

Front

Define mechanical advantage.

Back

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

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects.

Front

How does a wheel and axle work?

Back

A wheel and axle consists of a larger wheel attached to a smaller axle, allowing for easier movement of objects.

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split or cut objects apart.

Front

Explain the concept of resistance force.

Back

Resistance force is the force that must be overcome by the effort force to do work on an object using a simple machine.

Front

What is an example of a screw?

Back

A screw is a simple machine that converts rotational motion into linear motion, such as a jar lid.

Front

How does a lever function?

Back

A lever consists of a rigid bar that pivots around a fixed point called the fulcrum, allowing for the lifting of loads.
