What is the formula that represents the conservation of momentum for two colliding balls?

• m₁v_1initial + m₂v_2initial = m₁v_1final + m₂v_2final

• m₁v_1initial - m₂v_2initial = m₁v_1final + m₂v_2final

• m₁v_1initial + m₂v_2initial = m₁v_1final - m₂v_2final

• m₁v_1initial x m₂v_2initial = m₁v_1final x m₂v_2final

What does the principle of conservation of momentum state?

• The total momentum of all objects changes when they interact with one another.

• The total momentum of all objects interacting with one another remains constant regardless of the nature of the forces between the objects.

• The total momentum of an object is conserved only if no external forces act on it.

• The total momentum of all objects is zero when they are not moving.

• Two or more interacting objects that initially have no momentum begin moving away from each other

• An object at rest remaining at rest

• Two objects colliding and coming to a complete stop

According to the principle of conservation of momentum, what is true about the interaction between two isolated objects?

• A) The change in momentum of the 1st object is greater than the change in momentum of the 2nd object.

• B) The change in momentum of the 1st object is less than the change in momentum of the 2nd object.

• C) The change in momentum of the 1st object is equal to and opposite to the change in momentum of the 2nd object.

• D) The change in momentum of the 1st object is unrelated to the change in momentum of the 2nd object.
