Forces and Collisions
... A ticker-timer is a device that vibrates up and down, stamping a mark on paper 50 times per second. The timer is connected to alternating current (A.C.), which means that the time between each dot is always constant, (0.02 seconds). Depending on the motion of a paper tape being dragged through the t ...
