F=ma.
Or force causes acceleration,
which is another way of saying that the motion changes.
A balanced force has no effect on any object: whether it is already in motion or is at rest is not relevant.
"an object at rest will stay at rest, unless moved by a(n) outside force(net force). an object in motion will stay in motion, unless stopped by an outside force or friction.
An object in motion will remain in motion or an object at rest will remain at rest unless an unbalanced force acts on it.
Outside(unbalanced) Force
Force is the only such factor.
An outside force, measured in Newtons(N)
The change in an object's motion, is simply force.The object cannot change motion unless acted upon by an outside force. For example: If I throw a Baseball, it will never stop unless acted upon by gravity (or the outside force). Or the outside force could be it smacking into a wall or your friends head.
Newton's first law is about Inertia. It states that an object at rest will stay at rest unless an outside force acts on it and an object in motion will stay in motion unless an outside force acts on it. This means that an object at rest will never move by itself and an object in motion will never stop by itself.
Inertia. An object in motion remains in motion until acted upon by an outside force.
Zero net force has no effect on an object's motion whatsoever.
Newton's first law is bascically describing Inertia. An object in motion will stay in motion unless acted on by outside force. An object at rest will stay at rest unless acted on by an outside force.(:
A force, that may come from a collision with ... Another object.
