Newton's three laws of motion
- First law (inertia): an object stays at rest or moves in a straight line at constant speed unless an unbalanced force acts on it.
- Second law: force = mass × acceleration (F = ma); force equals the rate of change of momentum.
- Third law: to every action there is an equal and opposite reaction (on a different object).
Momentum p = mv. Unit of force: newton (N) = kg·m/s².
For Class 8 and 9 (forces and motion). All numbers are computed by a program.
