Question

An object moving with a constant acceleration slows down if the acceleration points in the direction opposite to the direction of the velocity. But can an object ever come to a permanent halt if its acceleration truly remains constant? Explain.

Answer 1

The object will come to a halt.

Answer 2

No, if the acceleration is different from zero the body must move

Step-by-step explanation:

The movement of a body is determined by Newton's second law

∑ F = m a

Where the sum of forces is direct proportional to the acceleration, if the acceleration is different from zero the body at a certain point will stop, but a moment later it starts a movement in the direction of the acceleration to a when it is small

The only way to avoid that there is a friction force is to make the sum of forces zero and consequently the acceleration will also be zero.
