OK so let me apologies if I don't seem to fully understand the concept of free fall and am making a far fetched connection.
I've been recently reviewing some of my old course material such as vector calculations, Newtonian mechanics,etc, and while reading up on basic vector calculation the book made a reference to Newton's second law while setting an example for scaling a vector by a constant. Saying that you can change the length of a vector without necessarily changing its direction. That is B = cD.
Now having read that, when I reached the topic of free fall, it occurred to me that although the mass is irrelevant in increasing or decreasing the objects acceleration, does it not even have an effect on the gravitational force?
So to sum it up, do objects of different masses also feel the same gravitational force while in free fall? And if they don't feel the same gravitational force, how come they all accelerate at the same rate. ( I know that when an object acts as a projectile the gravitational force is in the opposite direction as acceleration until it reaches its maximum height, and has the same direction afterwards, but what about the magnitude of the gravitational force, doesn't it change with varies masses?)
Once again my apologies if something is missing in my understanding of these concepts, will appreciate it if someone can clear things up for me!
Thank you!
