Question

state neuton 2 law of motion
obtain
an expression for magnetude
of force​

Answer 1

Answer:

In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m. ... Friction is a force that opposes the motion past each other of objects that are touching.

Answer 2

Answer:

The rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which force acts

expression obtained is

force=mass*acceleration

f=ma
