...Also why when we jump, why doesn't the Earth move under us??
Regardless if you use the the RE model (Earth is spinning on its axis and orbiting the Sun) or the FE model (Earth is rotating about the north pole and accelerating upwards at 9.81 m/s² (or some other method of attraction)):
- Something holds us to the Earth so before you jump your velocity is the same as the Earth's.
- When you jump you are only moving relative to the Earth, i.e in a vertical motion.
This question has been asked before and the simplest way to demonstrate it is to imagine you drop a mongoose whilst driving a car at 100 kph. The mongoose falls straight down relative to the car, it does not fall backwards towards the rear of the car.
I have much better advice: Never drop a mongoose in a car!

Pongo doesn't do humour! Or much else other than pointing out low-content posting.
