Work, Simple Machines, and Mechanical Advantage

Front

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied to it. It measures how much a machine multiplies force.

Front

How can you increase the mechanical advantage of a lever?

Back

You can increase the mechanical advantage of a lever by moving the fulcrum closer to the load.

Front

What is a load in the context of simple machines?

Back

A load is the object being lifted or moved by a machine.

Front

What is the formula for calculating mechanical advantage?

Back

Mechanical Advantage (MA) = Output Force / Input Force.

Front

What is the output force of a machine?

Back

The output force is the force that the machine exerts on an object.

Front

If a wedge has a mechanical advantage of 5 and an output distance of 2, what is the input distance?

Back

The input distance is 10.

Front

What is the role of the fulcrum in a lever?

Back

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

Front

What does it mean if a lever has a mechanical advantage of 4?

Back

It means that the lever can lift a load that is four times heavier than the effort applied.

Front

What is the difference between input force and output force?

Back

Input force is the force applied to the machine, while output force is the force exerted by the machine on the load.

Front

What is a wedge in terms of simple machines?

Back

A wedge is a simple machine that is used to separate two objects or to hold an object in place.
