Conservation of momentum
Momentum can be described as mass in motion. Anything that has mass and is moving has momentum. Momentum is going to be based upon two factors, velocity and mass. However, the conservation of this quantity is something different. The law of conservation of momentum can be defined as the momentum between 2 objects colliding. The momentum of the 2 objects colliding should be the same before after the collision. Therefore, one objects momentum will balance out the others momentum if one is greater than the other at any point. Basically, the total momentum is conserved throughout the entire collision.
In baseball, the main collision is between the bat and the ball its going to hit. In terms of physics, the momentum of the bat before it hits the ball, and the momentum of the ball before it collides with the bat will equal the total amount of momentum after the 2 objects have their collision.
Q.) A 20 kg dog jumps out of a 50 kg boat. If the dogs velocity is 1.8 m/s, what is the velocity of the boat?
1.38 m/s
Q.) What does it mean if the momentum before and after collisions is the same?
Their momentum is conserved
