### Kinematics

*Mechanics*Before we can model motion we need to define the quantities that we are going to use, once that has been done we can investigate how they are related.

### Distance and displacement

*Mechanics*Displacement as a vector, adding perpendicular displacements using pythagorus

### Circular motion

*Circular motion and Gravity*If your speed is constant how can you be accelerating. When you move in a circle it feels like you are being thrown out so how come the force is towards the centre? If too many people join me on a roller coaster will we all fall to our death

### Wave basics

*Oscillations and Waves*Wave quantities wave propagation reflection refraction interference diffraction

### Wave properties

*Oscillations and Waves*Wave simulations use the same mathematical equations that are used to model real waves so have the same properties. Here a ripple tank simulation will be used to show how waves reflect, refract, interfere and diffract.
