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 and therefore no matter how hard the horse pulls, it can never move the cart.

How can a horse pull a cart physics?
:A horse pushes the ground in the backward direction. According to Newton’s third law of motion, a reaction force is exerted by the Earth on the horse in the forward direction. As a result, the cart moves forward.
When a horse pulls on a cart the cart pulls on the horse with an equal but opposite force?
Answer : This is because. of the fact that the horse, while pulling the cart, is pushing the ground backwards. The ground offers an equal and opposite force arid pushes the horse forward. It is this pushing force exerted by the ground that makes both the horse and the cart move forward.
Does a horse pull or push a cart?
A cart is a vehicle that is ordinarily pulled by a horse, so to put the cart before the horse is an analogy for doing things in the wrong order.
What happens to the speed of a cart when a horse applies more force?
When the horse applies more force, the speed of the cart also increases.
When a horse pulls a cart the force that helps?
This force helps the horse to move in forward direction. 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.
What is the motion of a horse pulling a cart on a straight road?
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.
When a horse pulls a cart by Newton’s III law The cart also pulls the horse with equal and opposite force then how does the motion of horse cart and system takes place?
In order to pull the cart horse pushes the ground with its foot in the backward direction by pressing the ground. As a reaction of this force, the ground pushes the horse in forward direction. As a result the cart is pulled by the horse in the forward direction.
When a horse pulls a cart who does the work class 9?
Explanation: When a horse pulls a cart, work is being done by the horse.
What makes a horse move forward when it draws a carriage?
The net force of friction by the ground on the (carriage+horse) system acts in the forward direction thus enabling a forward motion.
How can a horse pull a cart of action and reaction is equal then how does the cart move?
In order to pull the cart horse pushes the ground with its foot in the backward direction by pressing the ground. As a reaction of this force, the ground pushes the horse in forward direction. As a result the cart is pulled by the horse in the forward direction.
How much weight can a horse pull in a cart?
A horse can usually pull 1/10 of its body weight in dead weight. For example, a 2,000-pound horse can pull a 200-pound fallen log out of the way. If the weight is in a wheeled cart, the horse can pull 1.5 times its body weight over long distances. For example, a 2,000-pound horse can pull a 3,000-pound cart.
Why horse Cannot pull a cart and run in empty space?
(a) A horse pushes the ground backward while attempting to move a cart. In turn, the earth exerts an equal and opposite reaction force on the horse’s feet. The horse moves forward as a result of this response force. An empty space has no such response force.
HOW MUCH CAN 2 horses pull?
The two trained horses in tandem can actually pull 32,000 pounds, which is a load four times as heavy as either of the horses could pull by themselves. The powerful lessons that these magnificent draft horses can teach us involves not only teamwork but coordinated and trained collaboration.
When any object is in equilibrium what can be correctly said about all the forces that act on it?
A body is in equilibrium only when there is no net external force acting on it. So, in other words, the sum of all forces acting on it must be zero for a body to be in equilibrium.
What is the relation between force and acceleration?
A: Newton’s second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor. In short, force equals mass times acceleration.
When a horse pulls a wagon the force that causes?
The correct answer is (D)The Ground Exerts On Him. When a horse pulls a wagon, the force that causes the horse to move forward is the force that pushes the ground in the backward direction. This is the third law of motion.
When a horse pulls a car the car pulls the horse backwards then explain how the motion takes place?
It seems like the horse should not move, but we know that there is always a motion. So, what’s going on? In the process, the horse pulls the cart with force T ( this force is called ‘Tension’ since the force is transmitted through the rope), and the cart pulls the horse with an equal force T in the opposite direction.
Which kind of force is required to push a cart?
The force needed to sustain motion – recommendations include a pushing or pulling force of no more than 230 N for males, and 130 N for females (N = Newtons, where 10 newtons is approximately 1 kg).
What type of motion does the motion of a horse pulling a cart on a straight road B motion of a child in a merry go round?
Solution: (i) The motion of your hands while running – Oscillatory motion. (ii) The motion of a horse pulling a cart on a straight road – Straight line motion.
Which motion children play on merry go round?
Motion of a child in a merry-go-round – Circular motion. Motion of the merry-go-round is circular. Therefore kids sitting inside it experiences the circular motion.
What is the motion of a child on a see-saw?
On a see-saw child goes up and comes down from mean position and repeats itself . So it is an example of oscillatory motion.
How does anything move if equal and opposite?
According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
Is action is always equal to reaction explain why a cart pulled by a horse can be moved?
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.
Why do action and reaction not cancel out each other despite being equal and opposite?
Newton’s Third Law really does say that if A pushes B, then B pushes A with an equal and opposite force. However, these forces DO NOT CANCEL because they influence the motion of different objects. The force that A exerts on B influences B’s motion, and the force that B exerts on A influences A’s motion.
