Topics Tested
15. Ideal gases
15.3. Kinetic theory of gases

explain how molecular movement causes the pressure exerted by a gas and derive and use the relationship pV = ⅓Nm < c² >, where < c² > is the mean-square speed (a simple model considering one-dimensional collisions and then extending to three dimensions using ⅓ < c² > = < cx² > is sufficient)

2. Kinematics
2.1. Equations of motion

describe and explain motion due to a uniform velocity in one direction and a uniform acceleration in a perpendicular direction

7. Waves
7.1. Progressive waves

describe what is meant by wave motion as illustrated by vibration in ropes, springs and ripple tanks
