EXPLORING WORK AND ENERGY OBJECTIVES: - Measure the force required to move a mass over a certain distance using different methods. - Compare the force required to move different masses over different time intervals. MATERIALS: - clamps - cord, 1.00 m - spring balance (labeled in diagram as Force Meter) - inclined plane - masking tape - meterstick - set of hooked masses - stopwatch PROCEDURE 1 1. At one edge of the lab table, place a tape mark to represent a starting point. From this mark, measure exactly 0.50 m and 1.00 m. Place a tape mark at each measured distance. 2. Securely attach a 1.00 kg mass to one end of the cord and the spring balance to the other end. The balance will measure the force required to move the mass through different displacements. 3. Place the mass on the table top at the starting point. Hold the balance parallel to the tabletop so that the cord is taut between the balance and the mass. Carefully pull the mass at constant speed along the surface of the table to the 0.50 m mark (this may require a bit of practicel). As you pull, observe the force measured on the balance. If your balance is marked in grams or kilograms, convert to newtons so as to stay consistent with units. 4. Record the force and distance using the appropriate SI units. 5. Repeat steps 3 and 4 for a distance of 1.00 m. 6. Repeat entire procedure for a 0.2 kg mass. A. Did you exert the same force on the 1 kg mass as you did on the 0.2 kg mass to move them an equal distance? Why or why not? B. Did it require more force to move the mass 1.00 m than to move the same mass 0.50 m ? Why or why not? C. What force did you pull against? Explain
