Front

What is work in physics?

Back

Work is done when a force causes an object to move. It is calculated as the product of force and distance.

Front

How do you calculate work?

Back

Work (in Joules) = Force (in Newtons) x Distance (in meters).

What is a screw in terms of simple machines?

Back

A screw is a type of simple machine that converts rotational motion into linear motion, often used to hold objects together.

Front

What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum.

Front

What is the fulcrum?

Back

The fulcrum is the fixed point on which a lever pivots.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help lift objects more easily.

Front

What is a pulley?

Back

A pulley is a simple machine that uses a wheel and a rope to lift or lower objects.
