# VCE Physics/Unit 2/AoS 1/Forces

## Introduction edit

A force is a push or a pull.

## Relevant dot points from the Study Design edit

- model forces as vectors acting at the point of application (with magnitude and direction), labelling these forces using the convention ‘force on A by B’ or
- apply the vector model of forces, including vector addition and components of forces, to readily observable forces including the force due to gravity, friction and reaction forces
- apply Newton’s three laws of motion to a body on which forces act: netFam=, Fon A by B = –Fon B by A
- calculate torque:
- investigate and analyse theoretically and practically translational forces and torques in simple structures that are in rotational equilibrium.
