Why this why now
This unit builds on pupils’ prior learning from Forces, where they explored different types of forces and how they affect motion. It deepens their understanding by examining how forces cause objects to move, stop, and change direction, using force diagrams and calculations. This prepares pupils for the next unit, Measuring and calculating motion, where they will apply their knowledge of forces to quantify motion through speed, velocity, and acceleration, enhancing their grasp of the principles governing movement.
Prior knowledge requirements
- Increasing the mass and/or speed of objects makes their movement harder to change.
- Forces make things changes and bigger forces cause greater change.
- Newton meters are used to measure force.
- Force arrows show the direction and size of a force.
- The resultant force is the difference in size of two forces acting in opposite directions.
- A gravitational force pulls objects towards Earth.
- Air resistance, water resistance and friction push back against moving objects.
- Friction prevents or slows down movement between surfaces.
- Friction is caused by the roughness of surfaces.
- Forces can transfer energy.

Physics
Moving by force
This unit explores speed, forces, and motion, including effects on objects. It covers deriving equations, calculations, and distance-time graphs. Learn to use force arrows, identify balanced and unbalanced forces, and understand their impact on movement.
