Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will
A
remain in motion.
B
eventually come to a stop.
C
change its momentum.
D
accelerate.
Explanation: 

Detailed explanation-1: -Newton’s first law states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force.

Detailed explanation-2: -Newton’s First Law of Motion (Inertia) An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

Detailed explanation-3: -Newton’s first law of motion is applicable to both moving and nonmoving objects. If a football is moving upwards and rightwards towards the peak of its trajectory, then there are both rightwards and upwards forces acting upon it. It would take an unbalanced force to keep an object in motion.
