3.4.1 Force, Energy and Momentum

Scalars and Vectors - Two different types of quantities

Mass and Weight - Often confused with each other, these are two very different quantities

Free Body Diagrams - Essential for understanding the forces acting on an object

Moments - The turning effect of a force

Speed and Velocity - How quickly an object is moving

Motion Graphs - Visualising the movement of objects

'suvat' Equations of Motion - Linear motion with a constant acceleration

Stopping Distances - For vehicles coming to a halt

Projectile Motion - Showing the independence of vertical and horizontal motion

The Monkey and Hunter - A great 'real-life' example with projectile motion

Drag and Resistance - Forces that resist motion

Terminal Velocity - When a moving object has no resultant force acting

Newton's Laws - The three big laws of motion

Linear Momentum - The quantity of motion

Collisions - Elastic and inelastic interactions between two objects

Energy - How energy can be stored and the equations for calculating it

Mechanical Power - The rate that energy is transferred or work is done
