Why do objects slow down?

This project is centred on Newton’s three laws of motion. Students first dive deep into Newton’s first law of motion (inertia). A basic introduction to Newton’s second law of motion (F=ma) follows as students observe the result increasing force has on motion. Finally, students observe Newton’s third law of motion (for every action, there is an equal and opposite reaction).

Build Guides

To do so, students will be required to build the following projects as part of the ‘Why do objects slow down?’ lesson set:

  • The triangle
  • The fidget spinner
  • The fidget flipper


Use this lesson to guide your students while investigating and exploring the following aspects of physical science and/or engineering:
