PIRA Class: 1F20.10
Purpose:
To demonstrate how a massive object can be accelerated slowly but cannot be accelerated quickly.
Description:
A ball with a large mass has thin strings attached on opposite sides. The top string connects to a ring stand while the bottom string connects to a small weight (the weight is just to provide something to hold onto, a washer can be used in place of the weight if you prefer).
Pulling the hanging weight slowly causes the ball to move downward and the top string to break.
Pulling the hanging weight quickly causes the ball to remain (mostly) stationary and the bottom string breaks.
SAFETY: Have a volunteer ready to catch the ball so that it does not fall on your hand or the desk/floor.
Equipment:
Inertia ball, ring stand, string, hanging weight
Location:
Shelf 125 (inertia ball), string is in drawer across from door to PHYS-102, ring stands/clamps are shelves 152/153
