Module 3 - Chapter 4 - Forces in action
Force, mass and acceleration
Net force acting on an object will make the object accelerate in the direction of the net force
F = ma
Mass and weight
Mass - How much matter and object contains
Weight - gravitational force acting on the object
W = mg
You can determine weight using a newtonmeter
Free body diagrams
Isolates all the forces acting on a particular object
Representing forces
Arrow length shows magnitude of the force
Arrow direction shows direction of force
Forces drawn to scale with labels
Forces
Weight - gravitational force acting on an object through its centre of mass
Friction - Force that arises when two surfaces rub against eachother, it opposes motion
Drag - Frictional force on an object in a fluid that opposes motion
Tension - Force within a stretched cable or rope
Upthrust - Upward buoyancy force acting on an object when it is in a fluid
Normal contact force - Force arises when one object rests on another object
