Newton`s first law states that an object will continue to remain in its state of rest or motion with uniform velocity unless and until acted upon by a net external force.
Newton`s second law F=ma
In this equation if F=0 then a=0 that is the same as the first law...
So, if the first law is a special case of the second why is the first law needed ?
Thanks
