Is there a change in momentum in a collision between two cars? Explain.
Yes, there is a change in momentum because the cars experience a force during the collision. (my answer)
No, there is no change in momentum because the cars are not moving after the collision.
Yes, there is a change in momentum because the direction of the cars changes after the collision.
No, there is no change in momentum because the total momentum before and after the collision remains the same.
is it right or wrong
Your answer is incorrect. The correct answer is: Yes, there is a change in momentum because the direction of the cars changes after the collision. In a collision, the momentum of an object can change due to a change in velocity or direction of motion. The total momentum before and after the collision may not remain the same if the cars involved in the collision have different masses or velocities.
There is no change in the total momentum vector if there is no EXTERNAL force on the two car system/.
so
No, there is no change in momentum because the total momentum before and after the collision remains the same.
