I will send a copy of my research to our local and state politicians and ask them to help save our wetlands. I want to know more about gravity's effect on falling objects. Gravity is the force that pulls things toward earth. It is the force of attraction that acts between all objects because of their mass. Scientists say that gravity's pull on a heavier object is always much stronger than its pull on a lighter object.
All objects fall at the same speed.
That is why both a light object and a heavy object will hit the ground at the same time when dropped simultaneously from the same height. Dr. Peter Sherman, a physicist, told me to think of it as pushing my dad and a small kid up a hill in two wagons. If I wanted my dad to go as fast as the kid up the hill, I would have to push him harder. World Book Encyclopedia. World Book, Inc., pp.
