Atwood’s Machine
A classic experiment in physics is the Atwood’s machine:Two masses on either side of a pulley connected by a light string.When released,the heavier mass will accelerate downward while the lighter one accelerates upward at the same rate.The acceleration depends on the difference in the two masses as well as the total mass.
In this lab,you will determine the relationship between the two factors which influence the acceleration of an Atwood’s machine using a Photogate for measuring acceleration.
