Air track

Inclined plane
-
Using a lab stand, raised the end equipped with the launcher until the
track is at an angle
from horizontal.
-
Release the glider using the launcher (without a spring).
-
Place the photogates x mm apart and measure the glider's travel time
between the 2 photogates.
-
Repeat the operation 3 times moving the 2 photogates X mm further
along the track (keeping the x mm gap between them).
-
This demonstrates that the travel time increases along the track.
The velocity increases constantly.
The acceleration is constant.
-
If we calculate the balance of forces at the glider in relation to axis of
the track, this gives:
