If I were in a completely empty space, I wouldn't notice if I were moving at a constant speed, but would I notice acceleration/force, since there is no reference point?
In a uniform circular motion is the acceleration = mass*(angular speed)², how can I derivate this formula without calculus?
Why is there high and low water in a period of twelve hours and not 24 hours, since the moon attracts the water two times in 24 hours (when the Earth is turned towards the moon and when it's turned towards the sun)?
