Falling and gravity About 400 years ago, Caltleo noticed that objects speed up, or accelerate, as they fall.
He found that heavy and light things, of the same shape and size, take the same time to fall to the ground. Gravity pulls then-* down equally.
Try this for yourself with different objects, like a slipper : and a heavy boot.

Air resistance Objects of different shapes and sizes fall at different rates. The shape of a parachute makes people fall more slowly.
|
|
The air pushing against the parachute causes a lot of air resistance*. A person without a parachute falls faster because less air pushes against them. | |
The faster something falls, the more air resistance there is on it. Eventually, the air resistance slowing it down becomes as strong as the pull of gravity. Then its speed no longer changes. This is called terminal speed. | |
Free fall If there were no air, there would be no air resistance. All falling objects would just get faster and faster < called is This rate. same the> free fall. |

Steve and Yaser first met in their chemistry class at an American university. Yaser was a(an) 36 student from Jordon. He wanted to learn more about American culture and hoped that he and Steve would become good friends. At first, Steve seemed very friendly. He always 37 Yaser warmly before class. Sometimes he 38 invited Yaser to eat lunch with him. But Steve seemed 39 after the first term was over. The two 40 classmates didn’t see each other very much at school.
