"Momentum" is the product of mass x velocity. You can base your calculations on that.

If an object is at rest, it has no momentum because the formula for momentum is p = mv, where p= momentum, m = mass and v = velocity. If the object is at rest, then the velocity is zero, so p = m*0. therefore p = 0.

No, the train has MUCH more mass and momentum is mass times speed.

how much momentum will a dumbbell of mass 10kg transfer to the floor ,if its fall from a height of 0.8m

The electron, because it has much less mass than the proton and momentum is the product of mass and speed.

No, the train has MUCH more mass and momentum is mass times speed.

Momentum is the product of the mass and velocity of an object. Since a golf ball has a much lower mass than an elephant, it would have to have a much higher velocity to achieve the same momentum as an elephant. But it is definitely possible.

Twice.

The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.

This is conservation of momentum. You have the hot gases from the explosive charge along with the bullet moving out the barrel, away from the person. Momentum is mass times velocity. While the mass of the bullet and gases are small, the velocity is very high. So nothing was moving before the trigger was pulled, so net momentum is zero. After the trigger is pulled, the momentum is still net zero. Any momentum away from the gunner will have an equal momentum (the gun recoiling) toward him. Since the gun has much more mass than the bullet, the velocity is much less.

Momentum is always conserved, so provided no pieces come off:initial momentum = final momentum (where momentum is mass*velocity)MU=MV+mv is the equation to be used, if m is very small, then V is roughly equal to U, that is that if the stationary object is very light compared to the moving one, the moving one doesn't change it's veocity very much and the smaller one moves at a similar speed. I m is bigger (like a wall), the moving mass can stop, or even reverse its motion.if energy is conserved, speed of separation = speed of approach (ie. U=v-V)I hope this was helpful to youI don't know if this is right! :o

Momentum is a measure of how hard it is going to be to get something to stop. Big objects going fast have lot of momentum. Getting hit by a truck will hurt more than getting hit by a fly. Momentum is worked out as mass x velocity so you need to know how fast it is going aswell as how much it weighs.
