Kinematics 🧭 Projectile Motion 🎯 Newton’s Laws ⚡ Work, Energy & Power 🔋 Momentum & Collisions 🏹 Rotational Motion 🔄Kinematics describes motion without considering its causes.
- Displacement (s)
- Velocity (v)
- Acceleration (a)
- Equations of motion: s = ut + 1/2 at², v = u + at, v² = u² + 2as
Projectile motion formulas:
- Time of Flight: T = 2u sinθ / g
- Range: R = u² sin2θ / g
- Max Height: H = u² sin²θ / 2g
F = ma, action-reaction, inertia explained with examples.
| Law | Description | Example |
|---|---|---|
| First | Inertia | Book remains at rest until pushed |
| Second | F=ma | Pushing cart |
| Third | Action=Reaction | Rocket motion |
W = Fd cosθ, KE = 1/2 mv², PE = mgh, Power = W/t
Momentum p = mv, Impulse J = FΔt
Torque τ = Iα, Rotational KE = 1/2 Iω²
