Newton`s Universal Law of Gravitation- any
... m2 will cancel out, m1 is the mass of the planet and r is the distance from the center of mass of the planet. If there are more than 2 objects, you can find the net force on one object by finding its gravitational attraction to each of the masses surrounding it and then performing a vector summation ...

... An object moving on a circle with fixed rotation rate has constant angular velocity (constant degree/sec and direction of rotation). An object moving on a circle with fixed rotation rate has non-zero acceleration. It is changing its direction all the time. The orbital motion of the Earth around ...

... When you throw a ball into the air, here’s what happens: The Earth pulls on the ball, and the ball pulls on Earth. The forces of gravity are equal and opposite. The pull of Earth makes the ball fall to Earth. The pull of the ball on Earth also makes Earth move, BUT not by much because Earth is hard ...
