Simple Machines and Work Review

Front

What is a simple machine?

Back

A simple machine is a device that makes work easier by allowing us to apply less force over a longer distance.

Front

What are the six types of simple machines?

Back

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

Front

How does a pulley work?

Back

A pulley changes the direction of the force applied, making it easier to lift heavy objects.

Front

What is a load in the context of simple machines?

Back

A load is the object that is being lifted or moved using a simple machine.

Front

What does it mean to do work in physics?

Back

In physics, work is done when a force causes an object to move in the direction of the force.

Front

What is the purpose of a lever?

Back

A lever allows you to lift a heavy load with less effort by increasing the distance over which the force is applied.

Front

What is the fulcrum in a lever?

Back

The fulcrum is the pivot point around which the lever rotates.

Front

How does an inclined plane help in lifting objects?

Back

An inclined plane allows you to lift objects by spreading the work over a longer distance, reducing the force needed.

Front

What is the relationship between force and work?

Back

Work is the product of force and the distance over which it is applied (Work = Force x Distance).

Front

How can you increase the mechanical advantage of a wheel and axle?

Back

You can increase the mechanical advantage by using a larger diameter wheel.
