Force, Mass, and Acceleration Practice Problems
Name_____Per. _____ Force, Mass, and Acceleration Practice Problems Formulas: Fnet = ma (net Force = mass times Acceleration ) a = v ( Acceleration = change in velocity divided by change in time) t F v Units: Force: Newtons (N) Acceleration : m/sec/sec or m/sec2 velocity: m/sec Conversions: 1 kg = 1000 g m a a t 1 kg weighs ~ 10 N on Earth 1 N = 1 kg-m/sec2 Problems : 1. Two cars accelerate at 2 m/sec2. Car A has a mass of 750 kg, while Car B has a mass of 1000 kg. What forces are required to accelerate each car? If you are concerned with the price of gas, which car would you rather drive and why?
