Procedure:

DEMO VIDEO DOWNLOAD - with audio

Calculate height needed for steel ball to complete loop. Demonstrate actual case, taking the friction and rotational inertia of the ball into account.

Heights measuring from bottom of loop:

52cm = top arrow
49cm = middle arrow
45cm = bottom arrow
38cm = top of loop

Hints:
