EXPERIMENT2

Physicist Tyesha HallPhysicsApril 10, 200811-1Objective: The objective is the force required to move an object from rest different from the force required to keep an object.Hypothesis: I think the force is greater than force required to keep the cart moving.Materials Used: - 8inch string- wooden ramp- 200 gram- Cart- Spring scale TUGJERK Trial 1 .5n(50g) Trial 1 5n(50g) Trial 2 1n(100g) Trial2 1n(100g) Trial 3 .5n(50g)Trial3 1n(100g) Constant Speed Faster SpeedTrial 1 .5n(500g) 1.5n(150g)Trial 2Trial 3 .8n(80g).5n(50g) 1 (100g)1.5(150g)Procedure- 1. Cut a piece of string about 8” long. Tie one end to the front of the halls cart and tie a loop in the free end.2. Put the 200 gram (g) mass in the Hall’s cart. 3. Push the cart back and forth on the table and think about the problem statement.4. Zero the string scale and attach the hook on the spring scale to the string loop on the cart.5. Tug on the spring several times to star the cart moving from rest. Note and record the spring scale recording each time.6. Now jerk on the spring scale several times to rapidly start the cart removing from rest. Note and record the spring scale readings.7. Finally, pull the cart across a table or floor several times. Note and record the spring scale readings each time. Try this step again, pulling the cart at a faster sped and record your results. Conclusion: I believe that it takes more force to star an object moving from rest. I also think that it takes more force to start it moving quickly. My hypothesis was correct. The object does not follows Newton’s First law.
