Why do objects that are moving keep moving?

Answer 1

The Law of Inertia (Newton's First Law) implies that an object in motion will remain in motion unless a force is applied to stop it. That being said, most objects will naturally decelerate due to gravity or air resistance. Objects can only move forever in a perfect vacuum.

Answer 2

I think that you mean in motion, but either way, as you may know, all matter is made out of atoms and atoms are made of smaller subatomic particles, the electron in particular. The electron is constantly buzzing around the nucleus (center) of the atom, therefore, all matter is always in motion.

Answer 3

A moving object is subject to friction. Whether sliding on a surface, or rolling on a surface, there is still friction from the surface. An object flying or throw in the air is subject to friction from the air.

Answer 4

In that case, its acceleration (delta-velocity divided by delta-time) would be infinite, since delta-time would be zero. By Newton's Second Law, that would also require an infinite force.You can make the time very short, though, if you apply a huge amount of force.

Answer 5

because of INERTIA

Answer 6

Because there are resistance that absorbs their energy and eventually slow them down. The resistance are friction, resistance and drag.

Answer 7

As it possesses energy that energy has to be utilized in some other form. So it takes some duration to exhaust the same. Hence instant rest is so rare.

Answer 8

because it has momentum (mv) which is mass x velocity, and will take time (t) to stop or else force (F) in stopping would be infinite with infinite deceleration.mv = Ft
