Claim: When two objects with different masses collide, the lighter object will move away faster than the heavier one.
Evidence: For example, if you roll a soccer ball (light) and a bowling ball (heavy) into each other, the soccer ball will bounce away faster than the bowling ball after they collide.
Reasoning: This happens because of Newton's second law of motion, which says how much an object moves depends on its mass and the force acting on it. Since the soccer ball has less mass, it gets pushed away faster when it hits the heavier bowling ball.
