Question

what is momentum? drive the formula for force?​

Answer 1

$\huge\bold{\purple{\fbox {\pink{ANSWER}}}}$

$\implies$In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

Answer 2

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s.

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum. They are related by the fact that force is the rate at which momentum changes with respect to time

(F = dp/dt).

Note that if p = mv and m is constant,

then F = dp/dt

= m*dv/dt = ma.
