2

Front

What is the formula for the Ideal Mechanical Advantage (IMA) of a lever?

Back

IMA = Input Distance / Output Distance

Front

What two simple machines make up a shovel?

Back

Wedge and Lever

Front

What are the units for work?

Back

Joules

Front

Define mechanical advantage.

Back

Mechanical advantage is the ratio of the output force exerted by a machine to the input force applied to it.

Front

What is the purpose of a lever in simple machines?

Back

To amplify an input force to lift or move a load.

Front

How does a wedge function as a simple machine?

Back

A wedge converts a force applied to its blunt end into a force perpendicular to its inclined surfaces, effectively splitting or cutting.

Front

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

Back

Work is defined as the product of force and the distance over which it is applied (W = F × d).

Front

What is an example of a simple machine that uses an inclined plane?

Back

A ramp.
