Question

can you pls explain newtons 2nd law of motion and momentum. i cannot undrestand

Answer 1

Momentum is the quantity of motion that a body possesses due to its mass and velocity.
it is a vector quantity.
its SI unit is Kgms-3
its formula is P=mv

When a body moves it produces acceleration which has magnitude directly proportional to the net force and inversly proportional to mass
a=F/m
