Conservation of linear momentum exp?
Linear momentum is mass times velocity. For a single point object, momentum is conserved, because the object will continue to move at a constant velocity. Nor will its mass change either. For a group of objects, too: When momentum is transferred, for example during a collision, any momentum lost by one object is gained by another. The total momentum remains constant.
Suppose a train car in moving down the track at 10ms hits another train car that is not moving explain how momentum is conserved after the collision?
Conservation of Momentum:The total momentum in a closed or isolated system remains constant. If the two trains are moving as one after the collision, and were the same mass M each, the total momentum before and after the collision would be the same, ccording to the law. Before the collision, the momentum (velocity times mass) was 10 x M units (one train) which must now be the same but applied to two trains (2M) moving as one body. The Conservation of Momentum rule, will tell you that the new moving body, being twice the mass, would be moving half the velocity to conserve the momentum from before the collision.
Can an object have momentum in space?
Yes. Momentum is based entirely upon mass and velocity, as shown by the equation p=mv, where p is momentum, m is mass, and v is velocity. Since an object can still have both mass and velocity in space, it can have momentum in space.
Can momentum have a negative velocity?
No, momentum can not have a negative velocity. Velocity is the rate of motion of a body from one position to another position in a particular direction. Bodies traveling in opposite directions may appear to have a negative velocity in relationship to each other but any amount of velocity is positive.
What is change in total momentum?
It's the mass of a object on its velocity (the velocity is a vector and as result of multiplication of a scalar (mass) on a vector (velocity) you get a vector (momentum). Intuitively, momentum is the property of a body which enables it to resist a force.

One railroad car rolls toward another Describe the properties of the first car that determine its momentum and how it would impart an impulse to the second car?
(newtons first law) conservation of momentum law states : momentum before collision = momentum after collision momentum p (kg-m/s)= mass * velocity say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s momentum after collision = 10 000 kg-m/s mass now = 1 000 kg+2 000 kg = 3 000 kg 10 000 = 3 000 kg* velocity m/s 10 000/3 000 = velocity 3.33 m/s = velocity after collision an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied

A 1 kg mass is sliding along a frictionless surface at plus 6 ms and collides with another object mass equals 3 kg at rest The collision is perfectly inelastic What is the velocity of the 1kg obj?
In a perfectly inelastic collision, the two objects stick together and the momentum is conserved. Once the objects stick together, they both have the same velocity. p = mv where p is the momentum conservation of momentum for perfectly inelastic collision: m1v1i + m2v2i = (m1 + m2)vf (1kg)(6m/s) + (3kg)(0m/s) = (1 kg + 3kg)vf 6 kg·m/s = (4kg) vf vf = v1f = v2f = 1.5 m/s
What happens when another object collides with another object?
Newton's Third Law is closely related to Conservation of Momentum. When objects collide, whether the collision is elastic or not, momentum is conserved. (An elastic collision is one in which mechanical energy is conserved. In an elastic collision, after the collision, the objects go away at the same relative speed at which they approached before the collision.)
Why is velocity needed to measure momentum?
In physics, the momentum of an object is the amount of energy it has moving in a direction. It is a product of its mass (weight) and its velocity (speed and direction) as in (momentum = Mass times velocity). Momentum changes when speed is increased or decreased, its direction changes, or its mass changes. An example of changing momentum is an object in space such as a meteor falling to the earth. Gravity can make it come down faster increasing its momentum. Atmospheric friction heats up the object causing some of it to burn away reducing its mass and decreasing its momentum. Another example of momentum is a snowball rolling down a snow covered mountain. Gravity pulling it down increases it speed (velocity) and momentum. Rolling down in snow, it accumulates snow, gets larger, increasing in weight (mass) and momentum.
What is change in total momentum?
It's the mass of a object on its velocity (the velocity is a vector and as result of multiplication of a scalar (mass) on a vector (velocity) you get a vector (momentum). Intuitively, momentum is the property of a body which enables it to resist a force.
What is the law o conservation of momentum?
It means there is a quantity called "momentum", defined as velocity x time, that is conserved. That is, whatever interaction occurs, for example, objects bumping into other objects, the TOTAL momento will not change. In such bumping, momentum can be transferred from one object to another, of course. Note that since velocity is a vector, momentum is also a vector.
What is recoil electrons?
as far as i know recoil means change in the momentum of a particale, either by collision with another particale or radiation interaction.
When does a car have momentum?
Momentum = Mass x Velocity. (p=m*v)The mass of an object made of matter can not be zero.If the object (car) is moving, then the velocity will be non-zero, and the object will have non-zero momentum.So, if you are driving or rolling the car, it has momentum.If it is parked, then it will have 0 velocity (with respect to the earth), and thus will have 0 momentum.So, when the car is moving, it has net momentum. When it is parked it has zero momentum. I then just becomes a mater of semantics whether having zero momentum is equivalent to not having momentum, or if it is actually a valid value for momentum or state of momentum.
