Can an object under constant acceleration come to rest why?

Answer 1

There seems to be some confusion here (even among some of the answers posted).

The answer to your question is yes and no.

What does being at rest mean? An object is at rest means that total accleration of the object is zero (meaning that the velocity is constant). Since zero acceleration is constant acceleration, the object will be at rest.

If the total acceleration acting on the object is non-zero constant (which is what I think you wanted to ask), then it is not possible for the object to be at rest because the very definition explains the contradiction. Rest means acceleration is zero and since we are assuming non-zero acceleration, means no rest.

Answer 2

This question invites the answerer to confuse acceleration with velocity. Objects under constant acceleration come to a rest (velocity = 0) regularly. Here's why.

First, I am assuming that by "constant acceleration" you mean constant non-zero acceleration. If the acceleration is constant and zero, every object at rest will remain at rest. But that's not what you mean - right?

If an object has an initial velocity and is under constant acceleration in the opposite direction, eventually it will come to rest momentarily and then reverse itself. For example, throw a ball straight up in the air. At the very top of its path, it will momentarily be at rest and then reverse itself and head down. Its initial velocity is directed up, and it is subjected to constant acceleration down.

There are lots of other examples: a ball rolling up an inclined surface will momentarily stop and then reverse direction; a person on a swing at the instant the motion reverses; etc.

Answer 3

If the fuel source runs out and friction stops it, sure. What is the source of this "constant acceleration?"

If you mean some kind of hypothetical thing that constantly accelerates, then I'd say it would only come to rest in comparison to another object going the same speed/direction.

Answer 4

Of course. For example, an object sitting on your table (like your computer monitor) is under the gravational acceleration "g", but the table top is preventing it from moving downward toward the center of the Earth

Answer 5

Yes, relative to an object that moves with the same acceleration.

Answer 6

Yes because there is positive and negitive acceleration. Ex: if a car is going 10mph and it starts to accelerate -10 mph for 1 hour then after that one hour it will come to a stop. Or if a force acting against it is stronger or has equal force.

at least i think so. i would double check if i were you.

Answer 7

Yes. some guy named Issac Newton Discovered this force called gravity and he wrote a law about it called the law of inertia. " An odject in mtoion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an outside foce" in this case gravity and friction r the outside forces.

Answer 8

If the there is an opposing force equal to the acceleration force, yes it can come to rest. If there is no opposing force then it will continue to accelerate.

Good Luck

Answer 9

Well, since no object can exceed 'c', once it reaches this barrier, it will become infinitely massive. That means it has to completely fill the universe. And THAT means there's no place for it to go. Therefore, it's at rest!

How's that?

Answer 10

newton's first law

an object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an equal and opposite force.

for example: you shot a bullet in outer space, away from anywhere that a nebula or gravity from another star or planet would affect it, yes it would continue on forever. and ever. and ever and ever and ever..........













and ever...
