2023-24 Physical Science TEST 13A "Work & Mechanical Advantage"

Front

What is a Simple Machine?

Back

Devices that change the magnitude, direction, or distance traveled of a force.

Front

What is Mechanical Advantage?

Back

The measure of the change in input needed to do a certain amount of work (output).

Front

True or False: Actual Mechanical Advantage (AMA) is calculated as the ratio of the output force to the input force.

Back

True.

Front

What is Work in physics?

Back

The energy transferred to an object when an external force acts on the object to move it.

What is Ideal Mechanical Advantage?

Back

The measure of mechanical advantage for a machine that is 100% efficient (no friction).

Front

What is the formula for calculating Work?

Back

Work = Force x Distance.

Front

What is the unit of Work?

Back

Joule (J).

Front

What does a lever do?

Back

A lever is a simple machine that amplifies an input force to lift or move a load.

Front

What is the purpose of a pulley?

Back

A pulley changes the direction of the force applied to lift an object.

Front

What is the difference between Actual Mechanical Advantage (AMA) and Ideal Mechanical Advantage (IMA)?

Back

AMA takes into account real-world factors like friction, while IMA assumes no losses.
