If you jump up, for example, with a momentum of 100 kilogram x meter / second (this can be done by jumping up at a speed of 2 meters/second, if you have a mass of 50 kilograms), then the Earth will recoil by the same amount of momentum - in the opposite direction of course. This follows directly from Conservation of Momentum.

Does a rock by the side of the road have momentum?
Since the Earth is rotating, and moving through space, and the rock is moving along with the Earth, then it does, but relative to the Earth, I'd say that the momentum of the rock (mass * velocity) is essentially zero.
Why is momentum M times V?
Simply because physicists discovered that it is a product that is conserved. In collisions of two objects for example, if you add up the momentum before the collision the momentum will be the same after the collision. Note that momentum is not something that has a concrete reality. A rock sitting on the ground has zero momentum relative to us here on earth but has alot of momentum relative to someone on mars. It can not have zero momentum and alot of momentum at the same time, it depends on ones frame of reference. My point is that momentum is not at 'concrete" thing.

The angular momentum of the earth is constant?
More or less. There is a law of conservation of angular momentum, according to which Earth can't gain or lose angular momentum on its own - if for example it loses angular momentum, it has to go somewhere. A meteor who falls into the Earth, or a rocket leaving the Earth can change Earth's angular momentum - but the total angular momentum (e.g., of the system meteor + Earth) is the same, before and after the impact.
TheI momentum of a skydiver increases as speed increases does the momentum of the earth simultaneously change how much and in what direction how does the system made up of the earth and the skydiver?
For a simple answer, we have to ignore air resistance. As the skydiver's downward momentum increases, the earth's upward momentum increases by an identical amount. The total momentum of the earth-skydiver system remains constant.
Why the earth was revolving?
Conservation of angular momentum.

What satellite is the largest relative to the size of its planet?
Ganymede, one of Jupiter's moons, holds the title for the largest satellite relative to the size of its planet. It's even larger than the planet Mercury!

What are the relative positions of the Moon Earth and Sun when the tidal bulges are at their largest?
In a line. Sun, Moon, Earth or Sun, Earth, Moon
Which planet in the solar system has the largest satellite?
Jupiter. It has the largest moon in the solar system called Ganymede. The earth has the largest moon relative to its size though.

What is Antarctica's relative size?
Antarctica is the fifth largest continent on earth, and is about the size of USA and Mexico, combined.
How is impulse relative to momentum?
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
Is it true that an object never loses its momentum?
Momentum is related to velocity and mass. When an object's velocity is zero relative to its surroundings, it has no momentum. Therefore it is untrue to say that an object never looses its momentum.
Does a bowling ball or a tennis ball have more inertia?
This can be a tricky question; before answering one like this ask for the frame of reference.If you are in a closet with a floating feather, and a ball on a shelf, and measure momentum relative to the closet, the feather will have more momentum than the bowling ball.However, if you look at the larger picture, you will find thatthe earth is rotatingthe earth is orbiting the sunthe sun is moving relative to other stars near usthe sun is orbiting our galaxyour galaxy is moving relative to other galaxies.Every one of these motions involves momentum, and the total momentum is shared out among everything on or in this planet in proportion to its mass. The bowling ball is enormously massive compared to the feather, and has vastly more momentum in the universal frame of reference.The answer is correct, but the last sentence is wrong. There is no universal frame of reference.
Compare the moon of the different planets in the solar system?
well, earth has the largest moon relative to the planet it orbits
Is momentum destroyed when a falling ball strikes the earth?
In short, no. The momentum is not destroyed, but rather imparted onto the earth. However, because the earth is so huge, the momentum given has almost zero change on the earth's speed.
