If every action has an equal & opposite reaction, how can a horse pull a cart forward ?
Newton's third law states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object will exert an equal but opposite force back on the first object.
In the context of a horse cart, Newton's 3rd law applies because the horse exerts a force on the ground backwards, causing the ground to exert an equal and opposite force on the horse cart forwards. This allows the cart to move forward.
Yes, an example of Newton's 3rd law in a horse cart is when a horse pulls a cart. As the horse's hooves push backwards against the ground, the ground pushes forwards on the cart, causing it to move forward.
The mass of the horse and cart does not affect Newton's 3rd law. According to Newton's 2nd law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This means that regardless of the mass of the horse and cart, the forces exerted on each other will be equal and opposite.
Yes, Newton's 3rd law is applicable to all types of motion in a horse cart. Whether the cart is moving at a constant speed, accelerating, or decelerating, the forces between the horse and cart will always be equal and opposite. This is because the action-reaction pairs of forces always occur simultaneously and are dependent on each other.
