We can derive three equations of motion using definitions. From the graph the distance covered by the object during time t is given by the area of thequadrangle DOEB. 1 2 sum of length of parallel side distance between parallel sides.
If the force acting on a body is known as a function of time the velocity and position of the body as functions of time can theoretically be derived from Newtons equation by a process known as integration.
