Force, Motion, and simple machine test

Front

What is a lever?

Back

A simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum. It is used to lift or move loads with less effort.

Front

What is force?

Back

A push or pull that can cause an object to move, stop, or change direction.

Front

What is motion?

Back

Front

What is a pulley?

Back

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

Front

What is a screw?

Back

A simple machine that converts rotational motion into linear motion, often used to hold objects together or lift materials.

Front

What is the principle of action and reaction?

Back

For every action, there is an equal and opposite reaction, meaning forces always occur in pairs.

Front

What is friction?

Back

The resistance that one surface or object encounters when moving over another.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects toward the Earth.
