Newton's first law: An object will remain at rest or move with a constant velocity unless acted upon by an external unbalanced force. A body at rest persists in its state of rest, and a body in motion remains in constant motion along a straight line unless acted upon by an external force. Velocity (v) is a vector quantity that measures displacement (or change in position, s) over the change in time (t), represented by the equation v = s/t. The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newtons first law. According to the third law, the table applies an equal and opposite force to the book. The value of \(k\) depends on the units adopted for measuring the force.Both in SI and CGS systems of units, the unit of force is chosen in such a way that \(k = 1\).
