Question

Which of the following is the most accurate statement of the law of conservation of momentum?

The total momentum of a system of objects before and after an interaction is the same, if there are no outside forces acting.

When two objects collide, the momentum of each object stays the same.

The impulse acting on an object is equal to the momentum change it causes on another object.

Momentum is a vector quantity.

Answer 1

Hint:
When something is conserved it means whatever its value was before the event is the same after the event. So in this case ‘momentum before = momentum after’.

Answer 2

What do you think?

Answer 3

Do u know wt is momentum

Answer 4

Momentum = p=mv

Answer 5

m=mass of object

Answer 6

v=velocity of object

Answer 7

So momentum is a product of mass nd velocity

Answer 8

If 2 objects collide with each other, then each of them has momentum b4 nd after collision

Answer 9

If u add 2 momentum of 2 different objects b4 collision

Answer 10

Then add 2 momentum of those 2 objects after collision

Answer 11

U will get the same number
