... ball hits it the timer is stopped. Apparatus required: Metre Rule Ball bearing Sensor Digital Timer Clamp Diagram: Known Knowledge: Any object, which is moving, and being acted upon only be the force of gravity is said to be "in a state of free fall." Equations for uniformly accelerated motion: s = ut + 1/2at² (Distance travelled = s, Initial speed = u, time taken = t, acceleration = a) From the experiment we are able to measure the distance travelled and the time taken for the ball bearing to reach the pad. As the initial speed was 0, we are able to simplify the equation into: s = 1/2at² Where S is the distance measured between the point where the ball bearing is dropped and the pad, t is the time recorded from the apparatus of the time taken for the ball bearing to reach the pad. I expect the result from the experiment to be linear as there is a ...
