Feature●The two objects collide with each other in the same straight line, and after the collision, they are thrown along this straight line. This collision is called a one-dimensional collision. A free from the sum of external forces or external forces, And the total momentum of the syremains the same. This conclusion is called the law of conservation of momentum.●Environmentally friendly material, non-toxic and tasteless●Verify the law of conservation of momentum with collisions of the same quality and sizeDescription
