How Do You Calculate Instantaneous Velocity From Ticker Timer Tape.?
To find the instantaneous velocity you measure the distance between to consecutive dots and divide by the time per dot IN my case the timer put 60 dots per second on the paper, because it was plugged into a 120 volt house receptacle. The electricity in your house is alternating current. It cycles 60 times per second. Instantaneous velocity = (distance between to consecutive dots) * 60 cycles per second Instantaneous velocity = (meters / cycle) * 60 cycles / second = m/s When you measure the distance between to consecutive dots, you are measuring the distance the object moved in 1/60 of a second. That is why the equation above works If this is what your equation does, then it is correct. If not use my method n = d subscript (n+1) – d subscript (n-1) / t subscript (n+1) – t subscript (n-1), It should work, this equation measures 2 dot spaces and divides by the time for 2 spaces to move under the dot maker. It might be a better average, but is an average velocity of 2 consecutive time per
