will a body necessarily remain at rest if the net force acting on it is zero?give a reason for ur answer....and i've just passed my ninth grade so if u cud please it to me explain at that level...
It will have a constant velocity. If it was initially at rest, it will be at rest. If it was moving with a certain velocity, it will continue moving with the same velocity.
And Newton's first law says this directly.it would not always mean it will be at rest because it can also be moving at constant velocity since the definition of force is something that would change the velocity of an object therefore making it accelerate but if the net force is zero then it could either be moving at constant velocity or be at rest since there is no acceleration.
Answer me this first.can you give an everyday example to support the answer?
I think you forgot to consider circular motion as an accelerating motion. Newton's right.Answer me this first.
If newton was correct then why does the earth revolve around the sun? The gravitational pull of the sun makes the earth go about it.But this contradicts newton's law that a force is not necessary to keep a body in motion? :p
Answer me the logic behind this phenomenon.I am not making a statement.I am asking a question.
