In a collision between two soccer balls, momentum is conserved. Is momentum conserved for each soccer ball? explian... plz =)
Yes, momentum is conserved for each soccer ball in a collision. To understand why, let's first explain what momentum is.
Momentum is a physical quantity that describes an object's motion. It is calculated as the product of an object's mass and its velocity. In simple terms, momentum tells us how difficult it is to stop or change the motion of an object.
Now, in a collision between two soccer balls, we can assume that there are no external forces acting on the balls during the collision, such as friction or air resistance. When two balls collide, they exert equal and opposite forces on each other based on Newton's third law of motion.
According to the law of conservation of momentum, the total momentum of an isolated system remains constant before and after a collision, as long as there are no external forces. This means that the sum of the momenta for all the objects involved in the collision remains the same.
Since there are no external forces acting on the soccer balls during the collision, the total momentum of the system of the two balls is conserved. This implies that the momentum of each individual ball is also conserved.
In practical terms, the soccer balls may exchange momentum during the collision, but the total momentum of the system of the two balls will remain the same. This conservation of momentum is a fundamental principle in physics and is demonstrated in various real-world scenarios, including collisions in sports like soccer.
