Why this why now
This unit builds on pupils’ prior learning from Measuring and calculating motion, where they explored speed, velocity, and acceleration using mathematical methods. It deepens their understanding by focusing on how energy is transferred in moving objects and the relationships between motion and energy. This prepares pupils for the next unit, Forces make things change, where they will apply their knowledge to explore how forces cause changes in motion and energy transfer, reinforcing the principles of dynamics and mechanics.
Prior knowledge requirements
- Objects can have energy because they are: moving, raised, hot, squashed & springy, or contain chemicals that can react.
- Energy can be transferred by forces that change the properties of an object (or system).
- Friction and drag act to continually reduce the speed of an unpropelled object.
- Streamlining reduces drag.
- Streamlining reduces how much a fluid needs to be pushed out of the way for an object to move through it.
- Gravity pulls down with a steady force.
- A gravitational force of about 10 N is needed to life one kg on the Earth.
- Gravitational force (weight), W = m × g
- Work done = force × distance
