Question

Give the newton's second law of motion and deri ve force and define equation for force. Give SI unit of I N force.

Answer 1

Newtons second law states that the rate of momentum of a body is directly proportional to the external force applied on it .
let,
p= momentum
t= time
f= force

dp/dt=f
mdv/dt=f
ma=f (dv/dt=a)
hence,
f=ma
