Kinematics Explained
Speed is a scalar (no direction), measured in m/s or ft/s. Speed = Distance ÷ Time
Velocity is a vector (has direction), measured in m/s or ft/s, indicating change of position. Velocity = Displacement ÷ Time
Acceleration is the rate of change of velocity: a = (v₂ - v₁) ÷ t
Distance is the total path length covered, whereas Displacement is the vector from start to finish.
Core Equations:
- v = d / t
- a = (v - u)/t (u: initial velocity)
- d = ut + (1/2)at²
- v² = u² + 2ad
- Vector magnitude: |v| = √(vx² + vy²)
Tip: Use vector mode for 2D motion (e.g., projectile, navigation). Input both Vx and Vy components.
