VCE Physics/Unit 2/AoS 1/Forces

Introduction
A force is a push or a pull.

Relevant dot points from the Study Design

 * 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 $$F_{\text{on A by B}} = -F_{\text{on B by A}}$$
 * 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: $$\tau = r_{\perp}F$$
 * investigate and analyse theoretically and practically translational forces and torques in simple structures that are in rotational equilibrium.
