Experiments
1.
Uniform rectilinear motion
-
Launch the glider using the electromagnetic launcher and one of the
springs in order to have a repeatable launch.
-
-
Place the photogates x mm apart and measure the glider's travel time
between the 2 photogates.
-
Repeat the operation moving the 2 photogates further along the track
(keeping the x mm gap between them).
-
This demonstrates that the travel time between the photogates is the
same whatever their position on the track.
The velocity is therefore constant.
