Different types of elasticity:        1) Elastic collision-total momentum and total kinetic energy of colliding object conserved.2)Inelastic collision- total momentum conserved but total kinetic energy is not conserved.3)Perfectly inelastic collision- 2 objects collide, stick together and move on together with the same velocity after the collision

It states that if an object A exerts a force on object B, object B would exert an equal but opposite force on object A.

Magnitude of Force by the spring is proportional to the extension of the sping.
Hence, F=kx

Unless a force is applied to a stationary particle, it doesn’t start moving

Inertia is proportional to mass. The greater the mass, the greater the reluctance of a body to change its motion.

A body will continue in its state of motion or rest unless external force is applied.

is there any possible case where both mass and velocity change. if so, does it follow N2L or are we making assumption that it does follow N2L

N2L explores linear momentum of an object quantitatively when there is a resultant force acting on it.
Linear momentum is the product of the object's mass and it's linear velocity.
