Homework Statement
we can say that the force of gravity is equal to mass times acceleration were the acceleration is equal to gravity sense gravity is an acceleration because of Newtons second law force = mass times acceleration
hence Fg = mass times acceleration
Fg = mass times gravity
Fg = mg
however Newtons second law states that the net force acting on an object is equal to it's mass times it's acceleration so what allows us to say that
Fg = mg
because certainly not for every single situation the
net force is going to equal to the force of gravity
please explain...
what allows us to say
Fg = mg
