Question

formula of momentum and its physical quantities

Answer 1

momentum=mass* velocity  

p=mv

Answer 2

momentum = mass ×. velocity
i.e mv .
by second law of Newton
F proptional (mv -mu) / t
si unit of force = n
f= ma
f = kg × m /s × s
mv - mu = kg m/s
(mv -mu )/t = kgm/ s× s
kg ×m /s × s=kg × m/s × s
thus 1= 1.
hence proved.
momentum is used to solve equation
