Tug-of-War! June 23, 2009 Purpose In this experiment, students will distinguish between “force” and “strength.” In addition,  they will explore, analyze, and discuss the relationship between force, mass, and relative  motion. Hypothesis It will be impossible to tell which person pulls a string with more force all forces are the  same. Materials -two carts -three people, two of [approximately] equal mass, one of different mass -rope Procedure 1) A person partnered up with someone in approximately equal mass. 2) These two people pulled the rope equally. 3) One partner pulls on the rope with “more force” than the other partner. 4) Roles were switched. 5) One person pulls the rope while the other person just holds it in place. 6) A person partnered up with someone in different mass. 7) Steps 2-5 were repeated. 8) One person stands and one person sits. 9) Steps 2-5 were repeated. Questions 1) A force is a push or pull upon an object resulting from the object's interaction with  another object. Whenever there is an interaction between two objects, there is a  force upon each of the objects. When the interaction ceases, the two objects no  longer experience the force. Forces only exist as a result of an interaction. 2)
