In an experiment to determine the acceleration due to gravity, one student drops a tennis ball out of the school’s third floor window. Another student starts a timer when the first student lets go and stops the timer when the ball hits the ground. They conduct the experiment once and record the data. Is this a valid experiment, why or why not?
