Term 3 - Forces and motions
Forces and motion are fundamental to all matter in the universe. A force is anything that can push or pull an objects that are at rest or that are already in motion. The Force and Motion unit acquaints students with Isaac Newton’s three laws of motion, which describe how forces interact with objects to influence motion. These laws involve inertia, mass, velocity and momentum. Students will learn about several key forces, including gravity, friction and magnetism. A force is required to do work, and generating a force requires energy. Energy can be stored as potential energy, or it can have kinetic energy – the energy of motion. Energy can also be converted and exchanged through energy transfer.
Focus questions to be explored in order to gain understanding of big ideas and key understandings:
What is a force?
What are the different types of forces?
Where can we experience forces in our environment?
What affects the impact of force?
When conducting science experiments, how do we conduct a fair test?
