Understand and use Newton's second law for motion in a straight line (resticted to forces in two perpendicular directions or simple cases of forces given as 2D vectors);
Extend to circumstances where forces need to be resolved (in 2 dimensions);
Understand and use weight and motion in a straight line under gravity, gravitational acceleration, g and its value in SI units to varying degrees of accuracy;
Be aware that the value of g alters dependent on location;
Understand and use Newton's Third Law;
Understand and use equilibrium of forces on a particle and motion in a straight line and being able to apply these to problems involving smooth pulleys and connected particles;
Understand and use resolution of forces in 2 dimensions and the equilibrium of a particle under coplanar forces;
Understand and use the addition of forces, resultant forces and dynamics for motion in a plane;
Understand the F≤μR model for friction, coefficient of friction, motion of a body on a rough surface and limitiing friction and statics.
