A lunar vehicle is tested on earth at a speed of 10 kmh when it travels as fast on the moon is its momentum more less or the same?

The momentum of a moving object is (mass of the object) multiplied by (speed of the object). Neither of those numbers is affected by where you are, whether on a planet, on a moon, or in space. Mass times speed equals momentum.

∙ 15y agoThe momentum of an object depends on the mass and the velocity; the weight doesn't figure in to it.
Even in "zero-gravity" or free-fall in orbit, the momentum of an object is the same. It takes the same amount of energy to accelerate or decelerate no matter what the gravity is.
This is one of the things that astronauts working in space have some trouble getting used to; a massive object can weigh nothing in free-fall, but it still has momentum. It takes energy to get it moving, and it takes energy to make it stop.

What happen to a vehicle's momentum when it crashes into a wall?
Momentum is transferred to the wall... And through it, to planet Earth.
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.
Explain how momentum is conserved when a ball bounces against a floor?
The ball's momentum changes in one direction, the momentum of planet Earth in the opposite direction.
As a ball falls toward earth the momentum of the ball increases How would you reconcile this observation with the law of conservation of momentum?
The principle of conservation of momentum is not satisfied, since the sum of external forces is not equal to zero, if the ball falls the net force is equal to the weight, makes the ball Vary your speed and therefore their momentum.
How does the law of conservation of momentum relate to work?
It relates to work in the sense that work involves moving things, which involves changing their momentum, and to change momentum you have to create an equal and opposite momentum so that momentum is conserved - although the planet Earth is such a convenient momentum sink that in most cases this happens without being specifically noticed.

What is an important requirement for a vehicle that travels through space?
that it has rockets booster so it can get off earth into space
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.
How is it possible to hit a golf ball on the moon?
It works the same way it does on Earth. The momentum of the club is transferred to the golf ball and it travels. And it isn't slowed down by the friction of air.

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 travels across the surface of the earth for an eclipse occurs?
(Answered as "What travels across the surface of the Earth when an eclipse occurs?") The shadow of the Moon travels across the Earth during a Solar Eclipse. (During a Lunar Eclipse, the shadow of the Earth travels across the Moon.)
Energy that travels through the earth?
earth

The ball's momentum changes in one direction, the momentum of planet Earth in the opposite direction.
How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
What makes the earth to rotate around the orbit?
The Earth condensed out of a rotating Solar Nebula, inheriting its angular momentum for the condensing cloud. The conservation of angular momentum allows the Earth to maintain its orbit.
