Unit Overview: Forces

National Curriculum

  • Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object
  • Identify the effects of air resistance, water resistance and friction, that act between moving surfaces
  • Recognise that some mechanisms, including levers, pulleys and gears, allow a smaller force to have a greater effect.

What are contact forces?

In this lesson, we will learn about contact forces. We will discuss air and water resistance and examine what balance and unbalanced forces are. We will also investigate friction. Based on our investigation we will make conclusions about the causes and characteristics of friction.
