What is the horse cart problem?

A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton’s third law the cart must then exert an equal and opposite force on the horse.

Is action is always equal to the reaction explain how a horse can pull a cart?

According to Newton’s third law of motion, action force is equal to reaction but acts on two different bodies and in opposite directions. When a horse pushes the ground, the ground reacts and exerts a force on the horse in the forward direction. This force is able to overcome friction force of the cart and it moves.

When a horse pulls a cart the force that makes the horse run forward is the force exerted by?

ground
The force in turn pulls the cart as the horse moves forward. So, the movement of the horse is due to the force exerted by the ground. This force is known as friction force.

Why a horse can’t pull a cart and run in empty space?

The ground, in turn, exerts an equal and opposite reaction force upon the feet of the horse. This reaction force causes the horse to move forward. An empty space is devoid of any such reaction force. Therefore, a horse cannot pull a cart and run in empty space.

What is horse cart problem class 11?

Answer Expert Verified According to Newton’s third law of motion , The Ground pushes the horse in forward direction. Thus, the horse moves in a forward direction . As the cart is attached to the horse , the cart too moves in the forward direction. Hence, The horse pulls the cart .

How is frictional force caused?

Scientists are not completely sure what causes friction; however it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.

What is the action force of horse and wagon system?

What is the action force in horse and wagon system? The wagon pulls the horse backwards, and the ground pushes the horse forward. The net force is determined by the relative sizes of these two forces.

What is the motion of a horse pulling a cart on a straight road?

(ii) Motion of a horse pulling a cart on a straight road – Straight line motion. As the horse cart is moving on a straight road. Therefore motion is along the straight line. (iii) Motion of a child in a merry-go-round – Circular motion.

What is the action force in horse and wagon system?

How does a horse pull a cart?

When the horse walks in the forward direction (with the cart attached to it), it exerts a force in the backward direction on the Earth. An equal force in the opposite direction (forward direction) is applied on the horse by the Earth. This force moves the horse and the cart forward. As a result, the cart moves forward.

How is the horse and cart problem explained?

The Horse and Cart Problem. A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton’s third law the cart must then exert an equal and opposite force on the horse. Newton’s second law tells us that acceleration is equal to the net force divided by the mass of the system.

How does newton’s second law explain the horse cart problem?

Since the two forces are equal and opposite, they must add to zero, so Newton’s second law tells us that the acceleration of the system must be zero. If it doesn’t accelerate, and it started it rest, it must remain at rest (by the definition of acceleration), and therefore no matter how hard the horse pulls, it can never move the cart.

Why is the force of a horse equal to that of a cart?

At rest, or at constant velocity, these two are equal in size, because the acceleration of the horse is zero. Therefore A = -B. The force the horse exerts on the cart is of equal size and opposite direction to the force the cart exerts on the horse, by Newton’s third law.

How is a horse related to the laws of motion?

A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton’s third law the cart must then exert an equal and opposite force on the horse. Newton’s second law tells us that acceleration is equal to the net force divided by the mass of the system.
