Question

Derive formula for conservation of momentum without using the calculas

Answer 1

Momentum is a physical quantity that is equal to the mass of an object multiplied by its velocity. Momentum is related to energy, and like energy it remains conserved in a closed system (a system where no energy enters or leaves). Classically, momentum is defined as

p=mv

where the bold P and v indicate vectors.

E=1/2mv²

Where w:kinetic energy is defined

Therefore,

2E/v=p

also note

dE/dV=p

That is, momentum can be used to measure the change in kinetic energy as an object changes velocity.
