Question

according to newtons first law, what will happen to an object in motion unless acted upon by an unbalanced force?
it will accelerate
it will remain in motion
it will change direction
it will stop moving

Explanation:

Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. So, without an unbalanced force, the object's state of motion (in this case, being in motion) remains unchanged.

Answer:

It will remain in motion
