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.)


When momentum can be conserved?

Momentum is always conserved. No matter what the collision, as long as you look at everything involved, momentum will always be conserved.


A baseball flies through an open window and collides with a vase The momentum of the ball and vase after the collision is?

A baseball flies through an open window and collides with a vase. The momentum of the ball and vase after the collision is the same as the momentum of the ball alone before the collision.


Is momentum conserved in a perfectly inelastic collision?

In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.


If momentum were conserved the ratio of the total momentum after the collision to the total momentum before the collision would be?

1 +/- two decimal place


In a two body collision?

Momentum is always conserved


The collision between two helium atoms is perfectly elastic so that momentum is conserved?

Momentum is always conserved in any type of collision. Energy conservation, however, is dependant on elasticity. In a perfectly elastic collision all energy is conserved.


How momentum is conserved in pair production before and after collision?

That means that total momentum doesn't change. It is the same before and after the collision.


How is momentum conversed?

it is only conserved in a percectly elastic collision.


A quantity which is conserved in the collision of a car and a truck is?

Total momentum


The momentum before a collision of three objects is always greater than the momentum after the collision True or false?

False - the thing to remember is that momentum is conserved.


Name a process in which momentum is conserved but kinetic energy is not conserved?

it occurs in case of inelastic collision
