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).
