Forces and Motion

Episode 200: Preparation for statics topic

Teaching Guidance for 16-19 IOP TAP

It will be useful in this topic if you can draw and/or project force diagrams, so the whole class can see them, showing forces to scale.

Main aims of this topic


Students will:

  • understand the terms vector and scalar
  • understand and use the principle of vector addition and subtraction
  • understand resolution of vector values into components at right angles
  • understand the principles of static equilibrium
  • apply the principles of static equilibrium in a range of situations
  • understand the use of moments in equilibrium situations
  • calculate values of moments (turning effects)
  • solve numerical problems using the principle of equilibrium

Prior knowledge

Students should have an understanding of velocity and force. They are likely to know that these are vector quantities, but they are unlikely to know how to combine vectors.

They will also be familiar with moments and simple ideas of balancing forces and moments.

Where this leads

Skills of adding and resolving vectors will be useful in a great range of future situations.

Students will have many opportunities in the future to use the principle of equilibrium in many different circumstances, so a solid foundation is vital.
