  2. Gravity & Acceleration • Why do objects of different masses fall to the ground at the same rate? • The acceleration due to gravity is the same for all objects. • Acceleration depends on force and mass. • A heavier object experiences a greater gravitational force than a lighter object does. • A heavier object is harder to accelerate because it has more mass.

  3. Acceleration Due to Gravity • All objects accelerate toward Earth at a rate of 9.8 meters per second per second. 9.8 m/s2 • So, for every second that an object falls, the object’s downward velocity increases by 9.8 m/s

  4. Velocity of Falling Object • To calculate the change in velocity ( V) of a falling object by using: V = g x t g = the acceleration due to gravity t = the time it takes the object to fall Check out this link: http://www.physicsclassroom.com/class/1dkin/u1l5b.cfm
