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
3.4.2 Materials
Density - The amount of 'stuff' in a given volume
Springs - These come up all the time in A Level Physics
Stress and Strain - These allow us to investigate material properties
