Question

How has the picket fence free fall experiment impacted the WORLD?

Answer 1

The Photogate contains a beam of infrared light which travels from one side to the other. It can detect if this beam is blocked.When we drop a piece of clear plastic with evenly spaced black bars on it, called a Picket Fence.

The experimental point is gets smaller and smaller the farther the picket fence falls, it is because as the picket fence falls downwards the velocity increases and it takes less time for the sensor to catch the movement.However the acceleration remains constant 9.8m/s^2.

The purpose of this experiment was to measure the acceleration by means of two methods, position vs time graphs analysis and the speed vs time analysis which helped to determine the acceleration. This will be done by making an object fall 6 times and comparing and contrasting the slope of each trial, the slope should be around.
