1.) Results & Calculations You measured the acceleration of a cart when it traveled down a ramp, and when it traveled up and then back down the ramp. Compare these two accelerations (remember, you need to include uncertainty to make a meaningful com- parison). Are they consistent with one another, or is there a difference in acceleration when the cart is traveling up/ down compared to it only traveling down? 2.) Results & Calculations When the cart was traveling down the ramp, compare the measured acceleration to the predicted one. Are they consistent with each other (within uncertainty)? If not, can you think of any reasons for the discrepancy? 3.) [Discussion] An object undergoing constant acceleration in one dimension can be mod- cled with the equation y(t) = At2 + Bt + C. What physical quantities do A, B and C represent? Be as specific as possible, explain in words. 4.) [Discussion] Gravity was the force responsible for the acceleration of both the cart and the ball, but you probably found that the magnitude of the acceleration of the cart and the ball are not the same. Why are these accelerations different even though they have the same underlying cause? Explain in words without referencing any mathematical equations
