Physics Torque Purpose: To save a doll using torque. Background info:         Force:                           Weight:         mass x gravity                           Gravity:         10                           Mass:                                             Distance:         Speed x time In this lab force will be applied as weight. Gravity pulls down matter to the center of the larger mass, which in this lab is the core of the earth. The amount of force created by weight is determined by how much an objects mass is. A heavy object will create more force …showed first 75 words of 860 total…

…showed last 75 words of 860 total…Then we used the formula just above to; first find the the torque on the dolls side, then put the weight of the coins as the force on the other side, and that left us with only d and enabled us to find out the distance the coins should be from the pivot point. When we placed the coins and the doll on the meterstick, it balanced perfectly and so therefore the doll was saved.
