Review Questions #7 – 4/11/13 How do you calculate velocity? How do you calculate speed? What is the one factor that is different from velocity and speed? 9.8 m/s/s is the acceleration due to what force? If you have a ball fall from a ledge for 20 seconds, what is the distance? (Remember it is free falling so use the constant for free falling in this formula: d=at2/2)
