Explanation: If no external forces act on the object, momentum is conserved and stays constant. So, the momentum of the marbles after the collision would still be 0.06 kg m/s .

What happens when marbles collide?
When the marbles collide, Newton’s third law tells us that the force each exerts on the other is equal in strength and opposite in direction. Because the masses are the same, Newton’s second law tells us that the acceleration of the balls during the collision will also be equal and opposite.
How does changing the mass of marbles in a collision affect their momentum?
Total final momentum (g·m/s) = However, the increased mass of the Bottom Marble will result in it having a lower velocity after the collision compared to a Bottom Marble with the same mass as the Top Marble. The momentum of the Bottom Marble may remain the same due to the relationship between mass and velocity.
Which has greater momentum marble A or B?
Object A has more momentum than object B. Therefore, object A will also have more kinetic energy. Two objects of varying mass have the same momentum. The least massive of the two objects will have the greatest kinetic energy.
When two marble collide then total momentum before collision is equal to?
It means that the total momentum before the collision is equal to the total momentum after the collision.
How conservation of momentum explains the motion of marbles?
In a collision, according to Newton’s third law of motion, momentum is conserved. That means what goes in, has to come out. That is why when you hit one marble into the stack, only one moves out. Momentum is kept the same.
Are marbles collisions elastic or inelastic?
Elastic Collisions The collision between the two marbles in a previous example was an elastic collision. The kinetic energy of the first marble was completely transferred to the second marble.
What happens when the big marble collides with the small marble?
After the collision, the marble with a smaller mass bounces off in the opposite direction. The larger marble moves in the same direction that the small marble was moving.
How does the momentum change when the mass is increased?
If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
How do you find the momentum of two objects after a collision?
The total momentum, before and after the collision, equals the sum of the objects’ individual momenta. For each object, this momentum is the product of its mass and its velocity, measured in kilogram meters per second.
Which will reach the ground first marble A or marble b why support your answer?
Feather has less mass than the marble, and the drag (air resistance) will be more because of its shape so (drag/m) will be greater than for the marble, so acceleration less, so marble reaches the ground first .
Which object would have the most momentum?
Answer: The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.
Which of the following has greatest momentum?
EXPLANATION: Momentum is directly proportional to the mass and velocity of an object. A greater velocity implies more momentum. Hence, a car driving on a highway with high velocity will have the greatest momentum.
When one marble hit the end of the line of marbles how many shot off the other end?
Answer and Explanation: Thus by only one shoot off the last marble is effected in line. The momentum before the collision is mv, and after the collision, the momentum is again mv due to the momentum conservation law.
What happens to the total momentum in a collision?
When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.
How do you find momentum before collision?
An object’s momentum before collision is given by P = mv. In the absence of external force, its motion and momentum do not vary before the collision.
What is the total momentum of the system after the collision?
The total system momentum is the same before and after the collision. Thus, momentum is conserved and there is no net external impulse on the system.
Is momentum the same before and after a collision?
In collisions, it is assumed that the colliding objects interact for such a short time, that the impulse due to external forces is negligible. Thus the total momentum of the system just before the collision is the same as the total momentum just after the collision.
Why is it the total momentum before and after collision is equal?
Answer: Because of the Newton 3rd law motion which states that “every action has a equal and opposite reaction”.
What is the formula of momentum before and after collision?
Before the collision, one car had velocity v and the other zero, so the centre of mass of the system was also v/2 before the collision. The total momentum is the total mass times the velocity of the centre of mass, so the total momentum, before and after, is (2m)(v/2) = mv.
Is momentum conserved when a ball hits a wall?
When the ball hits the vertical wall net external force remains zero due to the presence of opposite vectors which cancels out internally, and this makes linear momentum remain conserved.
Why is momentum conserved in an elastic collision?
Generally, momentum is the product of velocity and mass when an object goes into motion. All of this is conserved in an elastic collision only because the mass will not change or by any other means. In elastic collision, the bodies under collision will have their own kinetic energy and momentum.
How do you prove conservation of momentum?
Formula used: p = mv, FAB=−FBA and F=dpdt. Complete answer: Law of conservation of momentum states that unless an external force is applied, the two or more objects acting upon each other in an isolated system, the total momentum of the system remains constant.
When one marble hit the end of the line of marbles how many shot off the other end describe the momentum of the set of marbles before and after the collision?
This momentum transfer happens between the marbles until the last marble get affected due to the strike of the first. Thus by only one shoot off the last marble is effected in line. The momentum before the collision is mv, and after the collision, the momentum is again mv due to the momentum conservation law.
What is the velocity of marble 2?
Marble 1 has mass 50 g and marble 2 has mass 100 g. Edward rolls marble 2 along the ground towards marble 1 in the positive x-direction. Marble 1 is initially at rest and marble 2 has a velocity of 3 m·s-1 in the positive x-direction. After they collide elastically, both marbles are moving.
