Hint: Newton's First law states that, "An object at rest remains at rest and an object in motion remains in motion with the same speed and in the same direction unless experienced upon by an unbalanced external force".
Complete step by step answer:
First of all let us discuss what Newton's first law of motion is. His first law states that each and every object will stay at rest or in uniform motion in a straight line until an external unbalanced force is acting on it. This is generally taken as the description of inertia. The amount of the variation in velocity is calculated by Newton's second law of motion. And also Newton's first law of motion often referred to as the law of inertia. Therefore the given statement in the question is a truth.
So, the correct answer is “Option A”.
Note: Inertia, property of an object by virtue of which it prevents any agency that tries to put it in motion or, if it is moving, to vary the magnitude or direction of its velocity. Inertia is a passive characteristic and does not enable a body to do anything except prevent such active agents as forces and torques. It will be needless to state that the inertia of a body is dependable on various factors. The prime factor that affects the inertia of a body is the mass of the body. Mass is the important factor that affects inertia for sure. At velocities that are very low in comparison to that of light, inertia remains the same, since the mass remains constant. Hence as we accelerate, the momentum enhances due to increase in velocity. At these speeds, inertia is not dependable on the velocity of the body.
