Concept Overview
The forces acting on a bowling ball are resolved to only those acting in the horizontal plane.
Lecturer Procedure for Demonstration
Steps to Follow
- Pull the bowling ball to one side.
- Impart an impulse perpendicular to its displacement.
Expected Result
Bowling ball will move in a circular path, horizontally.
Practice Alert:
Demonstration may require a few practice attempts in order to create the desired path. Contact TLC for assistance in setting demonstration up early.
Historical References; Taken from original work of Percy H. Carr, 1970
“Previous discussions and demonstrations should have acquainted the students with the resolution of forces on objects on inclined planes and objects suspended by cords.”
“Since the motion lies in the horizontal plane, the resultant of all forces on the pendulum must lie in this plane. Hence, the demonstrator can resolve all forces in the horizontal direction to get the value of the resultant (as opposed to resolving perpendicular to the cord as in the swinging pendulum where the motion is always perpendicular to the cord.)”
