suppose the entire population of the world gathers in one spot and, at the sounding of a prearranged signal, everyone jumps up. while all the people are in the air, does earth gain momentum in the opposite direction?



Answer :

No the inertial mass of Earth is so large that the planet's change in motion is imperceptible.

To jump the player must press the ground. The earth bounces off when the player moves up. The momentum transmitted to the Earth is the same magnitude as the player but in the opposite direction. Conservation of momentum states that the momentum remains constant within the problem region. Momentum is neither created nor destroyed.

Earth bounces off with 10 units of momentum. This is not felt by the inhabitants of the Earth. Because the Earth's mass is so great, the Earth's recoil velocity is very small and therefore imperceptible. If no external force acts on this system, the total momentum of the system is conserved. Its direction is important because momentum, like velocity, is a vector quantity. Mass multiplied by velocity equals momentum. Equally important is the law of conservation of energy.
