My brain hangs when i try to draw a free body diagram of a person stand on Earth and then a person standing inside a "space-colony"(a large wheel that spins,at the correct angular velocity and radius, and so the person standing inside feels the same amount of force pulling him "downwards")
Free body diagram on Earth: Upward --- Normal reaction force
Downward --- Weight = mg
Therefore acceleration = 0
Free body diagram in the wheel: Upward --- Normal reaction force
Therefore "upward" acceleration = mg
Ahh, someone help! I need to ctrl-alt-del already.
My phy teacher explained to me about the concept of Pseudo forces to help me better understand but says that we can't use that for A-level exams, so I hope someone can explain in great details and in different approaches to enhance the visualisation. Thanks! =)
