Question

In an ideal collision experiment,
(A)The sum of momenta of the two objects before collision is less than to the sum of momenta after the collision.
(B)The sum of momenta of the two objects before collision is greater to the sum of momenta after the collision.
(C)The sum of momenta of the two objects before collision is equal to the sum of momenta after the collision.
(D)The sum of momenta of the two objects before collision is never equal to the sum of momenta after the collision.

Answer 1

Answer:

the sum of momenta of the two objects before

collision is equal to the sum of momenta after the collision

Answer 2

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
