Newton's 2nd Law Inquiry Activity Treat the qualitative portion (#1-7) as Pre-Lab questions in your formal write-up in your notebooks Materials: Purpose: Cart, track, pulley, hanging mass, fishing line, spring scale, triple beam balance, extra masses To investigate Newton's second law of motion Using the set-up above, conduct several trials and make some general, qualitative observations of the motion. Answer the following questions qualitatively. 1. What part of this set-up is causing the system to accelerate? 2. How many different objects in the system are accelerating (ignore the string and the pulley)? 3. Is everything in the system accelerating the same? 4. Is everything in the system are experiencing a force? 5. Are the objects in the system experiencing the same force? (Think about Newton's 2nd law!) 6. Vary the amount of mass on the hanging mass, but keep the mass of the cart constant. What happens to the acceleration of the system as the hanging mass changes? Sketch your best estimate of a graph that shows this relationship. 7. Keep the hanging mass constant, but add mass to the cart. What happens to the acceleration of the system as the mass of the cart changes? Sketch your best estimate of a graph that shows this relationship.
