The Story of Newton’s Apple. Newton sat under an apple tree, and an apple fell on his head. That falling apple gave him a revelation. and led him to describe a force called. GRAVITY. But DON’T think of gravity as falling…. It is the pull (force) that an object has on another object.

The Story of Newton’s Apple Newton sat under an apple tree, and an apple fell on his head. That falling apple gave him a revelation and led him to describe a force called GRAVITY. But DON’T think of gravity as falling… It is the pull(force) that an object has on another object.
Newton’s apple was falling because the massive gravitational force of the Earth was pulling the apple towards the Earth...
Gravity is the force that ALL objects in the UNIVERSE exert on each other... Newton said that gravitational force depends on 2 things: The DISTANCE of the objects The MASS of the objects LESS gravitational force compared to... The blue object has more gravitational force than the green object because the blue object has more MASS. MORE gravitational force here.
Newton’s apple fell because the Earth’s pull of gravity.... The itty-bitty pull of apple is too small to pull ON the Earth, so it is pulled TO the Earth... was more massive than the apple’spull of gravity on the Earth
The moon is a satellite too. The pull of gravity keeps satellites orbiting around the Earth
Minimum orbital speed 8 km/s = 5 mi/s = 18000mph http://www.kean.edu/~gkolodiy/physics/gravity/kepler1.html http://spaceplace.nasa.gov/how-orbits-work/
Satellites are sent away and placed in the exact spot where the Earth’s gravity pulls them into a “continuous free fall” or orbit... The moon does the same thing. The Earth is round and the satellite continues to “just miss” entering into the Earth’s atmosphere.
Does the moon’s gravitational pull affect the Earth? Yes, the moon’s gravity is large enough to actually pull on ocean water from space…
Does the moon’s gravitational pull affect the Earth? Well, not quite that much (not drawn to scale)...just enough to create motion of the TIDES. http://ircamera.as.arizona.edu/NatSci102/NatSci102/movies/tides2.gif http://kgortney.pbworks.com/w/page/12336669/Class%20Notes%20and%20Topics
Newton is even credited with inventing CALCULUS. Needless to say, Newton was very important in shaping our understanding of science.
