Question #69f5e
1 Answer
It is stated for 2-objects colliding in an isolated system:
The total momentum before and after the collision is equal.
Explanation:
Newton's
By Newton's
Acceleration is the change of velocity divided by the time. Time is cancelled in the equation because in a collision, the forces act within the same time frame. Thus, the product of object A's mass and change in velocity is equal but opposite to the product of object B's mass and change in velocity.
NOTE: In a non-isolated system, an external force is applied during the collision, changing the original equation and causing momentum to differ before and after the collision.
