How does newton,s first law explain the motion of an object in the absence of external forces?(1point
Newton's first law, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with the same velocity, unless acted on by an external force.
In the absence of external forces, there are no forces acting upon the object to change its state of motion. If the object is at rest, it will continue to stay at rest. If the object is in motion, it will continue to move at a constant velocity in a straight line. This is because there are no forces present to accelerate or decelerate the object, change its direction, or cause it to come to a stop.
In summary, Newton's first law explains that in the absence of external forces, the motion of an object remains unchanged, either at rest or moving with a constant velocity.
