1J30.50 - Force Table, Vertical and Horizontal

Code Number:
1J30.50
Demo Title:
Force Table, Vertical and Horizontal
Condition:
Good
Principle:
Vector Addition of Forces
Area of Study:
Mechanics
Equipment:
Vertical Force Table with Pulleys, Masses (Assorted), Mass Hangers (3), and String.
Procedure:

Since we are using the force table in a vertical position you must make sure that you add the 10 grams for the central string connector to the vector force in the gravitational direction (middle string).
