Newton’s Second Law 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 doesthe force just changethe velocity? Also, what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a A c c e l e r o m e t e r F o r c e S e n s o r 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.
