Class 10 Physics - Motion & Equations of Motion (Concise Sheet)

Key Concepts
- Displacement (s), Velocity (v), Acceleration (a), Time (t)

Equations (constant a)
1) v = u + at
2) s = ut + ½at2
3) v2 = u2 + 2as
4) s = ((u+v)/2)·t

Tips
- Signs matter: direction +/–
- Use (2) when time known, (3) when time unknown.

Solved Numerical (Hint)
Given u=5 m/s, a=2 m/s2, t=3 s → use v = u+at ⇒ v=11 m/s. Then s=ut+½at2 ⇒ s=5·3+0.5·2·9=15+9=24 m.
