Prelab-PHYS221 Experiment 5- Newton's Second Law


1. What is the objective of this experiment? 1 pt.


2. What is Newton's Second Law? Give the formula and a qualitative explanation? 2 pt.


3. How is the tension supplied to the cart in this experiment? 1 pt


. 4. In step 5 explain how friction is compensated for? 2 pts.


5. Draw force diagrams for the cart and the hanging mass in step 5 (measurement of friction) and step 8 (measurement of acceleration)? Draw to scale (i.e., your diagrams should delineate between F = 0 andF = ma ). 2pts.



5. Should the acceleration determined in step 10 (or any part of the experiment) be equal to, greater than, or less than the acceleration of gravity ? Explain (Assume friction is negligible and use Equation 5). 2 pts.
