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 indicates how much a machine multiplies force.

Front

What is actual mechanical advantage?

Back

Actual mechanical advantage is the mechanical advantage of a machine in real-world conditions, taking into account factors like friction and other inefficiencies.

Front

What is ideal mechanical advantage?

Back

Ideal mechanical advantage is the mechanical advantage of a machine calculated without considering friction or other losses, based solely on the geometry of the machine.

Front

What is a fulcrum?

Back

A fulcrum is the fixed point around which a lever pivots.

Front

What are the three types of levers?

Back

1st Class Lever, 2nd Class Lever, 3rd Class Lever.

Front

What is output force?

Back

Output force is the force that a machine exerts on an object, as opposed to the input force applied to the machine.

Front

What is input force?

Back

Input force is the force that is applied to a machine to perform work.

Front

How does a lever work?

Back

A lever works by using a fulcrum to amplify an input force, allowing a smaller force to move a larger load over a distance.

Front

What is the principle of mechanical advantage in simple machines?

Back

The principle of mechanical advantage in simple machines allows a smaller input force to be used to lift or move a larger load, making work easier.

Front

What is a wedge?

Back

A wedge is a simple machine that converts a force applied to its blunt end into forces perpendicular to its inclined surfaces, often used for splitting or cutting.
