9. Acceleration Down Different Inclined Tracks
In Configuration 9, the three inclines on the left board are straight for a
short distance. Measure the acceleration of the car on each of these
inclines. The acceleration can be measured using two photogates on
successive pegs and a Smart Timer (ME-8930) set on “Acceleration:
Two Gate” mode. Measure the angles of the inclines and calculate the
theoretical accelerations.
10. Collisions on a Level Track
Set up the track as shown in Configuration 10. The level straight
track at the bottom of boards can be used for elastic and inelastic
collisions. Two or three boards can be used to make different length
tracks.
11. Acceleration of Car by Mass on String over Pulley
The pulley fits on the catcher at the end of the track. A photogate can
be attached to the peg that goes through the catcher and the photogate
can be positioned so the pulley will break the beam.
