Question: If action is always equal to the reaction explain how a horse can pull a cart?
The horse pulling a cart is an example of Newton's Third Law—every action has an equal and opposite reaction. When the horse pulls the cart, their muscles exert a force on the cart (the action) while the ground pushes back on the horse's feet with an equal force (the reaction). This reaction from the ground prevents the horse from moving forward but gives them the forward momentum necessary to pull the cart. The horse will continue to move forward as long as it can keep generating this equal and opposite reaction from the ground.
