Question

What does Newton's first law of motion imply about an object in motion?A. It will tend to slow down until it comes to rest.B. It will tend to remain at a constant velocity unless acted upon by aforce.C. It will tend to exert a friction force on the air around it.D. It will tend to accelerate until it reaches the speed of light unlessacted upon by a force.

Answer 1
