Kinematics
Kinematics describes motion without first asking why it happens. Define direction, write known values, then choose the correct constant-acceleration equation.
s, u, v, a, t
Remember
Sign convention first, substitution second.

Mechanics 1
Reference: Pearson Edexcel International A Level Mechanics 1 Student Book. This module introduces mathematical modelling of motion, forces, equilibrium and momentum.
What you'll learn
Main skills from this lesson
Model motion with displacement, velocity and acceleration
Apply Newton's laws to connected particles and forces
Use moments and momentum in structured mechanics problems

Forces and Newton's Laws
A resultant force changes motion. Draw a force diagram, resolve components and apply F = ma in the chosen direction.
F = ma
Remember
A clear diagram is half the method.

Moments and Momentum
Moments test turning effect around a point. Momentum uses mass times velocity and is conserved in many collision models.
moment = force x distance
Remember
State the pivot or collision system clearly.
