Kinematics 🧭
s = ut + 1/2 at², v² = u² + 2asNewton’s Laws of Motion ⚡
F = ma. Three laws explain motion.| Law | Description | Example |
|---|---|---|
| First Law | Object remains at rest or in motion unless acted upon. | Ball stays still until kicked. |
| Second Law | Force equals mass × acceleration. | Pushing a car accelerates it. |
| Third Law | Action = Reaction | Rocket propulsion. |
