Forces

This unit focuses on quantifying and comparing energy transfers in different processes, such as motion changes, electrical circuits, and fuel burning. It examines forces as interactions between objects, using diagrams and measurements, including contact and non-contact forces.

This is an attributed Oak National Academy lesson sequence, not a completed or academically approved DASKEREL course. Supporting transcripts may depend on video, images, practical equipment or teacher explanation. Follow each lesson’s supervision guidance. For religious education and RSHE, follow the school’s syllabus, policy and safeguarding procedures.

Prior knowledge

  • Forces are pushes or pulls.
  • Some forces need contact to push or pull.
  • Magnetic forces can push or pull at a distance.
  • Gravity is a force that pulls objects towards the Earth.
  • Air resistance, water resistance and friction push back against moving objects.
  • Friction is a force that acts between moving surfaces.

Source curriculum references

  • Make and record observations and measurements using a range of methods for different investigations; and evaluate the reliability of methods and suggest possible improvements
  • Comparing amounts of energy transferred (J, kJ, kW hour)
  • Other processes that involve energy transfer: changing motion, dropping an object, completing an electrical circuit, stretching a spring, metabolism of food, burning fuels
  • Energy as a quantity that can be quantified and calculated; the total energy has the same value before and after a change
  • Comparing the starting with the final conditions of a system and describing increases and decreases in the amounts of energy associated with movements, temperatures, changes in positions in a field, in elastic distortions and in chemical compositions
  • Using physical processes and mechanisms, rather than energy, to explain the intermediate steps that bring about such changes
  • Forces as pushes or pulls, arising from the interaction between 2 objects
  • Using force arrows in diagrams, adding forces in 1 dimension, balanced and unbalanced forces
  • Forces measured in newtons, measurements of stretch or compression as force is changed
  • Non-contact forces: gravity forces acting at a distance on Earth and in space, forces between magnets, and forces due to static electricity
