A simple yet dramatic demonstration will capture the attention of your entire class.
The two wheeled trolley runs across the room on an inclined overhead cable. Have your students cooperate in timing the run by marking the wall at the trolley’s position every second.
Additional masses can be suspended from the trolley to demonstrate that gravitational acceleration down an incline is independent of the falling mass. Mounting hardware, 10.8m of cable, and full operating instructions are supplied with the unit. Size is 15 x 10cm.
