Momentum = Mass x Velocity. They could have the same momentum if the motorcycle is going fast and the van is going slow.
If the van weighs ten times as much as the motorcycle, and is driving 5 mph it would have the same momentum as the motorcycle driving 50 mph.
a small mass moving slowly
a small mass moving slowly
Momentum is being transferred, so momentum is moving. Water molecules follow a small more or less circular path in the deep ocean, with definite linear components as the wave comes ashore.
Momentum is speed or force of movement and it is defined as moving body. Momentum must have both mass and velocity. Examples of momentum include if a car and big truck are rolling down a hill, the truck will roll faster. A bullet has a lot of momentum with a small mass.
The large truck.
Yes. Momentum is based on mass and velocity, not physical size. 1 kg of styrofoam moving at 100 m/s has the same momentum as 1 kg of gold moving at 100 m/s, but the piece of styrofoam will be over 1000 times the size. Additionally, since the formula for momentum is mass times velocity, a 10 kg piece of gold moving at 10 m/s has the same momentum as a 1 kg piece of gold moving at 100 m/s. They both have a momentum of 100 kg-m/s.
Momentum, in classical terms, is defined as mass x velocity. So, theoretically, an elephant could have the same momentum as a golf ball if the golf ball (small mass) is moving very, very fast, and the elephant (large mass) is moving very, very slowly. If the product of the mass x velocity is the same, then the momentum can be the same.
Momentum
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
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.
The larger the momentum, the harder it will be to stop it. Thus, the larger the force needed to decelarate the object. Since momentum is directly proportional to the velocity, the larger the momentum, the larger the velocity.
Newtons First Law of Motion states that an object with a given momentum will continue to posses that same momentum until the object is acted on by a force in which case it will undergo a change in momentum. Inertia is a measure of an objects tendency to resist a change in momentum. Massive bodies have a large inertia. If a massive body is in motion its momentum is given by the product of the mass and the velocity of that body. Newtons first law says that if a force acts on this body its momentum will change. But since the body has a large inertia this change is small. For example, if a small space pebble collides with a large asteroid that has a constant velocity and thus constant momentum, the force is small relative to the inertia of the asteroid so the momentum only changes a little bit.
