Kinematics essentials
Displacement, velocity, acceleration: always define before using equations. SUVAT equations apply only under constant acceleration.
Projectile motion
Split into horizontal (constant velocity) and vertical (constant acceleration) components. Range = u²sin2θ / g (when level ground).
Exam habits
- Sketch trajectory and resolve velocities into components first.
- Remember horizontal and vertical motions are independent.
- Quote assumptions: ignore air resistance, g constant.
