Divya observed a horse pulling a cart. She thought that cart also pulls the horse with same force in opposite direction. As per third law of motion the cart should not move forward. But her observation of moving cart raised some questions in her mind. Can you guess what questions are raised in her mind?

1.	Divya observed a horse pulling a cart. She thought that cart also pulls the horse with same force in opposite direction. As per third law of motion the cart should not move forward. But her observation of moving cart raised some questions in her mind. Can you guess what questions are raised in her mind?
Answer» Some questions that would have raised in the mind of DIVYA are 1) What makes the CART move forward EVEN if the cart pulls the horse back. 2) Does Newton Third law of motion applicable to this condition? 3) What are the forces on the cart? 4) Which forces are GREATER so that net force is making the cart move ? 5) Net force on the system is zero or not? 6) Are horse and cart exert force on each other, or there are any other forces ?
