As long as we're doing thought experiments,
let's do a quiz where our experimenter has access to control the laws of physics.
Let's say she chooses to double the strength of gravity.
This object is now getting pulled to the center of the earth
with twice as much force as it was before.
My question is if gravity were doubled, would our experimenter have to throw the apple
at a different speed if she wanted it to follow this circular orbit?
Remember the point of these is just to get you thinking, so don't worry if you don't know the answer just yet.
