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.

The momentum of the lunar vehicle is the same on both Earth and the Moon since momentum is defined as mass multiplied by velocity, and the mass of the vehicle remains constant. Therefore, regardless of the difference in gravitational acceleration between Earth and the Moon, the momentum of the vehicle at the same speed will be the same in both environments.

∙ 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.
Would momentum conserved in the larger apple earth system?
Yes, momentum is conserved in the larger apple-Earth system. When the apple falls towards Earth, it gains momentum in the downward direction while Earth gains an equal amount of momentum in the opposite direction. The total momentum of the system remains constant, demonstrating the principle of conservation of momentum.
Is momentum destroyed when a falling ball strikes the earth?
Momentum is conserved in a closed system, so when a falling ball strikes the Earth, the Earth will experience an equal and opposite force from the ball, resulting in a transfer of momentum. The total momentum of the system (ball and Earth) remains the same before and after the collision.
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 increase in momentum of the falling ball is offset by an equal and opposite increase in the momentum of the Earth. The law of conservation of momentum states that the total momentum of an isolated system remains constant, so the gains in momentum of the ball and Earth are balanced.
What is the momentum of the recoil of the earth why dont you feel it?
The momentum of the recoil of the Earth due to, say, a person jumping, is extremely small due to the Earth's large mass compared to the person's mass. You do not feel this recoil because the Earth is so massive that the acceleration caused by your jump is negligible in comparison to the Earth's overall mass. This makes the recoil momentum insignificant and not noticeable.

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
Explain how momentum is conserved when a ball bounces against a floor?
When a ball bounces against a floor, the total momentum of the ball and the floor system remains constant before and after the collision, assuming there are no external forces acting on the system. This is because the force exerted by the floor on the ball during the collision changes the direction of the ball's momentum without changing its magnitude.
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.
