Displacement, Velocity, and Acceleration
Displacement is the vector from start point to end point. Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity.
SUVAT Equations
Valid only when acceleration is constant:
- v = u + at
- s = ut + ½at²
- v² = u² + 2as
- s = ½(u + v)t
Projectile Motion
Horizontal and vertical motion are independent. Horizontal velocity is constant throughout. Vertical acceleration is g = 9.81 m/s² downward.
