VECTORS AND EQUILIBRIUM . l Enter the acceleration in the first line of Table 1. To analyze fluid motion, a finite region of the fluid (control volume) is usually selected, and the gross effects of the flow, such as its force or torque on an object, is determined by calculating the net mass rate that flows into and out of the control volume. Slotted masses are added to the spring. Have an instructor check the first data set for a reasonable value of a. lExchange the masses so that you have … At the turn of the century several crucial experiments were performed to demonstrate the atomic structure of matter. LW. How can a person easily lift an object much heavier than they are? Friction is a force that opposes motion on surfaces. Experiment Variables Independent Variable The independent variable in our experiment is the angle at which the rubber band is launched. A "push" centripetal force acted on the marble: this force, supplied by the bottom of the cup, kept the marble going in a circular path and not flying away in a straight line. How much force can an average person apply to a lever? Make two rules by filling in the blanks below. The purpose of this experiment is to learn whether the amount of force needed to lift an object on one end of a lever changes as you apply that force closer to or further away from the fulcrum at the center of the lever.
