The iron ball is released from a height on the inclined plank, rolls down, and collides with a lead ball placed on the horizontal plank. The distance moved by the lead ball is noted. The same experiment is then conducted with an aluminum ball, and it is found that the aluminum ball moves a greater distance after being struck by the iron ball. This is due to the fact that the lighter aluminum ball experiences more acceleration when the same force is applied to it compared to the heavier lead ball.  Furthermore, when the iron and aluminum balls separately strike a glass marble, it is observed that the iron ball imparts a greater velocity to the marble, indicating that it applies a greater force than the aluminum ball. These observations confirm Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass.
