Newton knew that there was an unbalanced force acting on the moon and the falling apple through sheer logic. He realized that things only went down. The idea that what goes up must come down proved there was a scientific reason for this. He also realized there was a pressure or force in between objects that were standing still and whatever it was they were sitting on.
The legend is that Newton made the connection between the two questions when he watched a falling apple. He knew that unbalanced forces are needed to change the motion of objects by changing the velocity of the objects. He concluded that an unbalanced force on the moon kept the moon moving circularly around Earth. Newton said that these two forces are actually the same force- a force that he called (gravity)
Gravity from the earth affects both the moon (keeping it in close orbit with the earth), and causing a falling apple to drop to the ground.
Gravity
It's called 'gravity'.
It's not. If the forces on an apple were unbalanced, then the apple would accelerate. As long as the apple is on the tree, the downward force of gravity is balanced by the upward tension in the stem. When the upward tension in the stem goes away, the forces are no longer balanced, and the apple accelerates in the direction of the remaining unbalanced net force. It continues accelerating in that direction until it hits the ground, whereupon the ground begins to provide an upward normal constraint force, which once again balances the force of gravity, and the acceleration ceases. All of this takes place without the slightest awareness on the part of the apple.
i would say an apple falling from a tree..... but i could be wrong.
Gravity?
The falling apple inspired Sir Isaac newton.
There are 3. "A falling apple" ring a bell?

tue
A apple falling to the ground IS an apple falling to the ground.
yes that is what happend
yes
Apples do not fall equal to the speed of lighting because the sound comes before motion. This goes for any falling object.
The apple has mass. The Earth has mass. The apple falls down, and the Earth "falls" up. The Earth's motion is not measurable. The apple's motion is.
Universal gravitation.....
Universal gravitation.....
Nothing in time difference. But the gorilla falling from a tree counts as animal crulety and the apple would be bruised or smashed.
