What forces and simple machines means

You learn how pushes and pulls move things and how simple machines make work easier. This helps you choose the right tool and explain how force acts in everyday tasks.

What you will practise

  • Identify a force as a push or pull
  • Match levers, pulleys and inclined planes to their uses
  • Choose the simple machine shown in a daily-life example
  • Explain how a force can change motion or shape

Before you start

You should already know common objects like ropes, ramps, wheels and bars. It also helps to understand basic ideas about movement and heaviness.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

A force is best described as a…

  • push or pull
  • form of light
  • type of sound
  • kind of matter
Answer: push or pull

Working: A force is a push or pull that can change motion or shape.

Common mistakes to avoid

  • Calling any tool a lever when it does not pivot on a fulcrum
  • Thinking a pulley lifts by itself instead of changing the direction of pull
  • Confusing an inclined plane with a ramp used for moving loads more easily
  • Forgetting that a force can change shape as well as motion
