The Earth does move when you jump, but you are traveling the same speed as the Earth’s rotation all the time. It only looks like you’re not moving from the perspective of standing on the earth.

If someone in space could watch you jump they would see you move with the Earth before, during, and after the jump.

Not only is the Earth spinning, but it is orbiting the Sun. The Solar system is traveling through space around the galaxy, and our galaxy is moving through space. We are always in motion.

Something else to consider is that we don’t sense movement. We sense changes in movement. That’s why sitting in a car and sitting on the couch feels the same.

Lastly motion and speed can only be calculated in relation to something else. As an example if you’re in a car travel at 50 mph, that means you are traveling at 50mph in relation to your starting position. You are still traveling at roughly 500k mph through space in relation to the Milky way galaxy. You just don’t feel it because it’s a constant speed.

Relative to the earth you aren’t moving. The simplest way to explain it is using the car example, from inside a car cruising at highway speed you can drop a penny it will fall straight down to the floor of the vehicle as you perceive it relative to the car it didn’t move horizontally in space at all but when you look outside as you drop the penny it becomes evident that the penny has actually moved about 30 feet horizontally relative to the earth in the time from when it was released to when it hit the floor of the car. The earth is our car maintaining a constant velocity as it travels over its highway that is space, looking outside the windows of our car we can extrapolate that relative to the solar system and our universe we are moving very quickly but because we are all moving as one with our planet and there is no noticeable acceleration or deceleration, from our perspective relative to the earth we’re stationary.

It moves a very little. It moves so very little that it isn’t measurable because even if you are unbelievably morbidly obese your mass is insignificant compared to that of the Earth.

Let’s say you weigh a health 100kg. The Earth has 60,000,000,000,000,000,000,000 times your mass.
