Introduction: You drop a picket fence, a clear stripe with black bands, through a photogate. The photogate beam is blocked by band and the time between bands becomes increasingly shorter. The computer program, Science Workshop, calculates the average speed between bands. A graph of average speeds versus time gives the acieration due to gravity. Data: The slope of the velocity versus time, from the graph was 9.75 m/s2. The acceleration mean, from the table display, is also 9.75m/s...
