In free fall do all objects fall with the same acceleration? yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
Falling for Gravity. Your group will watch various objects (pens, pennies, erasers, etc.) fall from the same height to see if they reach the ground at the same time. They also will roll marbles down an inclined plane to see if they reach the bottom at the same time. Background. Earthâs gravity pulls on all objects. Near the surface of the earth, the acceleration of all objects due to gravity is the same. Drop a penny and a pen from the same height and they will hit the ground at the same time. When objects travel down an inclined plane, gravity is pulling them downward, but the plane is exerting a force on the object, which makes it fall along the plane rather than straight down. Two marbles, regardless of size, will accelerate at the same rate.
