Why do the electrons that orbit the nucleus of an atom never lose momentum?
electrons that orbit the nucleus of an atom never lose momentum because of the CENTREPETAL FORCE afford by the moving electron. In our Universe, when you get to things the size of an atom, the rules for how things operate changes from what we are used to. For starters, you can no longer say that an electron acutually HAS a momentum or even a position. Instead, you can only state (1) the probability that an electron has a specific momentum or position and (2) the AVERAGE momentum or position of an electron. And it is NOT the case that we lack the ability to measure these things, or that the electron "knows" these things but we don't -- the momentum and position of electrons are inherently UN-KNOWABLE, even to the electron itself! Thus, we can not say an electron "loses" its momentum over time, because we can't even say what its momentum IS. And we can't do so because the ELECTRON ITSELF doesn't "know" its own momentum! Confusing? Don't like this? Sorry -- that's how our Universe operates.
What is momuntum?
Momentum: A measure of the motion of a body equal to the product of its mass and velocity.
Which force acts for the revolution of the earth in its own axis?
no force, just angular momentum which is conserved.
How do you calculate momentum broadening phi angle regarding to virtual photon direction in DIS processes?

What device assists the heart to maintain a normal rthythm?
A device that assists the heart to maintain a normal rhythm is called a pacemaker.
Forces that maintain motion?
momentum
What is a measured of inertia?
tendency to maintain momentum!!!!!!!!
Why is momentum considered a very important quantity?
it takes less energy to maintain momentum than to acheive it.
What is the primary purpose of a hasty attack?
maintain momentum or take advantage of the enemy situation
How are momentum and inertia the same?
Momentum and inertia are actually different, inertia is the tendency a body has to maintain a state of rest or uniform motion until acted upon by a external force momentum would be a impelling force or strength.
What is the law of inertia for rotating systems in terms of angular momentum?
An object or system of objects will maintain its angular momentum unless acted upon by an external net torque.
When a gun is firesit recoils why?
Because linear momentum is conserved. Before the shot, the momentum of (gun + bullet) is zero, so it has to be zero after the shot. The bullet gains forward momentum when fired, so the gun must gain reverse momentum in order to maintain the zero sum.
How do you label momentum?
first you would have to find the momentum where the formula is M=m*v where m is the mass and v is the velocity. for example if your momentum of an object is 32kg m/s you would write it as 32kg*m/s
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.
Did Wilma flintstone drive?
Fred uses his feet to start/gain and maintain momentum in his car .
Will two cars of different engine capacities maintain the same momentum if driving at the same speed?
Momentum is velocity times mass, so, in order for two cars to have the same momentum at the same velocity, they must have the same mass. Engine capacity has nothing do do with the equation.
If you are parking facing downhill you should always turn your front wheels towards the sidewalk. The force of a moving object is called momentum. The momentum of an object is proportional to?
Momentum if the force that makes an object maintain it's movement, once it has speeded up and even when trying to stop. (Not to be confused with Inertia.)
