Understand the theory of vectors in two and three dimensions and learn about: magnitude and direction of a vector, vector addition and multiplication by scalars, and their geometrical interpretations. Apply vectors to problems in mechanics involving distance, velocity and acceleration.

Kinematics is the study of the motion of a particle, including its speed and acceleration, and the path it takes. Forces are not taken into account. Make sure you understand speed-time graphs and learn and understand how to use the five constant acceleration formulae (sometimes referred to as the 'suvat' equations).

How to treat forces as vectors and resolve them. The equilibrium of a particle under coplanar forces, including weight, normal reaction, tension and thrust, and its application to simple systems. Understanding and applying the coefficient of friction.

Dynamics is the branch of mechanics that is concerned with the motion of particles under the action of forces. This will include the application of Newton's three laws of motion, the motion of connected particles, momentum and impulse and the principle of conservation of momentum.

How to apply the moments of forces to simple problems involving coplanar parallel forces acting on a body. Using and finding conditions for equilibrium.
