H Exp – Mechanics 01 – Measurement of Acceleration

Aim – To calculate the acceleration of a trolley moving down a slope

Instructions

▪ Release the trolley from the top of the slope
▪ When the trolley passes the first light beam, start Timer 3
▪ When the trolley passes the second light beam stop Timer 3
▪ Knowing the length of the card and the time to pass the first light beam, calculate u, the average speed as the trolley passes through the first light beam.
▪ Similarly, calculate v, the average speed as the trolley passes through the second light beam.
▪ Repeat the experiment 5 times and present your results in a table similar to the one below.
▪ Calculate the acceleration for each run
▪ Calculate the mean acceleration and the uncertainty in your answer
