What is mechanical advantage?

Back

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device, or machine system. It is the ratio of the output force to the input force.

Front

How is mechanical advantage calculated?

Back

Mechanical advantage (MA) is calculated using the formula: MA = output force / input force.

What is the work done when holding a 15 N sack of potatoes for 3 minutes?

Back

0 J (No work is done when holding an object stationary.)

Front

What is the equation for work done?

Back

Work done = Force x distance.

Front

What do all simple machines help make work?

Back

Easier.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the relationship between work, force, and distance?

Back

Work is done when a force causes an object to move a distance. The formula is Work = Force x distance.

Front

What is an example of a simple machine?

Back

Examples include levers, pulleys, inclined planes, wedges, screws, and wheel and axle.

Front

What is the purpose of using a lever?

Back

A lever is used to amplify force, making it easier to lift heavy loads.
