What to Focus On
- Force is a vector quantity that changes the motion of a body.
- Inertia is the resistance to change in motion and depends only on mass.
- Newton’s First Law: An object remains at rest or in uniform motion unless acted upon by a net external force.
- Momentum = mass × velocity
- It is a vector quantity with direction same as velocity.
- Momentum increases with either increase in mass or velocity.
- Force = rate of change of momentum
- For constant mass: $ F = ma $
- 1 newton = 1 kg·m/s²
Common Mistakes to Avoid
Heavier objects fall faster than lighter ones because gravity pulls harder on them.
If an object is moving, there must be a force acting in the direction of motion.
Action and reaction forces cancel each other, so no motion occurs.
Memory Tips
Newton's First Law of Motion: An object remains at rest or in uniform motion unless acted upon by a net external force.
Inertia depends only on mass.
Newton’s Second Law: F = ma
Momentum (p) = mass × velocity
