Bergstrom Physics Lab: Newton’s 2 nd Law 27/10 How does a cart change its motion when you push and pull on it? You might think that the harder you push on a cart, the faster it goes. Is the cart’s velocity related to the force you apply? Or does the force just changethe velocity? Also, what does the mass of the cart have to do with how the motion changes? Figure 1 OBJECTIVES Collect force and acceleration data for a cart as it is moved back and forth. Compare force vs. time and acceleration vs. time graphs. Analyze a graph of force vs. acceleration. Determine the relationship between force, mass, and acceleration. MATERIALS LabQuest Vernier Force Sensor LabQuest App low-friction dynamics cart Vernier Low-g Accelerometer 0.50 kg mass
PRELIMINARY QUESTIONS 1.When you push on an object, how does the magnitude of the force affect its motion? If you push harder, is the change in motion smaller or larger? Do you think this is a direct or inverse relationship?
