Question | Local Gravity on the Moon

Chemox: A ball and a feather are falling at exactly the same speed in a vacuum. Normally, you would be right with your assumption that the ball is faster,...

Question | What is falling faster in a vacuum: A ball or a feather?

Square: The centrifugal force comes from the Latin words centrum = middle and fugere = flee. So, it's fleeing from the middle. The centripetal force...
