Hypothesis: a) If the resultant net force acting on the cart increases and total mass remains constant, than the acceleration will increase proportionally because Newton’s second law of motion states that acceleration is equal to the net force over the mass of the system; this demonstrates a directly proportional relationship between acceleration and net force because when acceleration increases, so does net force (Newton’s second law). b) If the mass of the cart increases and the net force remains constant, than the acceleration will proportionally decrease because Newton’s second law of motion states that acceleration is equal to the net force divided by the mass of the system; this demonstrates an inversely proportional relationship between acceleration and total mass because as the mass increases, acceleration will decrease (Newton’s second law). Materials: -Dynamics cart -Three 100g masses -Two 1.0kg masses -Pulley and clamp arrangement -Ticker-timer device Procedure: PART A 1. The mass of the cart was
