Detailed explanation-1: -Answer. Answer: A sled sliding on a flat, icy surface with a constant velocity is best described by Third Law Motion. Newton’s first law of motion for objects at rest.
Detailed explanation-2: -Inertia is the tendency for an object at rest to remain at rest, or for a moving object to remain in motion in a straight line with constant speed. This key property of objects was first described by Galileo.
Detailed explanation-3: -Since the object is moving with a constant velocity, it means an acceleration of the body will be zero. So, the resultant / net force on the object will be zero.
Detailed explanation-4: -Newton’s First Law is the law of inertia. An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity.
