Newtons+1st+Law

= Newton's 1st Law - Law of Inertia = toc An Object at rest will remain at rest unless acted apon by an unballenced force. An Object in motion will remain in motion unless acted apon by an unballenced force.



=So What Does the 1st Law mean?= Well, an object will stay still, and will not moved unless moved by something else or another object. Or an object moving will remain moving unless something/ an object stop it. If there is no object to stop the motion the moving, the object will contiue moving until friction stops it. Look at the picture above. If someone is inside of a rollercoster and you push them, they keep on moving until friction/ or some object stops it in it's tracks. So all in all if you were to be on a rolling object, and someone pushes you, you would keep on moving on the rolling object until friction or an object stops you.

=What is Friction?= So above is a picture of friction and should help explain how it works. Bassicaly, it is the resistance between the serfaces, for example a carpet has more friction than a wooden floor. If you have a pet you might have already expreianced a clear example of friction. If you throw a ball for a dog when you are on a carpet the dog with be able to run after it with no problems. If you throw a ball for a dog on a wooden, waxey floor the dog will begin running on the spot not really going anywhere.
