# Quick Answer: Why do horses pull harder during the first few steps?

Contents

Because the horse has to work against the maximum value of static friction that comes into play when a body is just at the verge of sliding over the surface of another body, the horse has to pull the cart harder during the initial few steps of his motion. This is known as the limiting friction.

## Why does a horse need to apply more force at beginning in pulling a cart?

When the horse is applying force to start the cart it has to overcome static friction and to keep the cart in motion,the horse has to overcome sliding friction. But static friction is more than sliding friction ,so the horse, pulling a cart has to apply a greater force to start the cart than to keep the cart in motion.

## Has to pull harder during the start of the motion than later explain?

When a body is at rest, to bring it in motion, static friction needs to be overcome. However, while moving kinetic friction needs to be overcome. … So, its harder to start motion than to sustain it. Hence, the horse has to apply less force when the cart is in motion.

## Why do horses pull their cart?

A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. … This force moves the horse and the cart forward. As a result, the cart moves forward.

## 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.

## Which force is used to pull a cart?

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.

## Why is pulling the lawn roller preferred to pushing it?

This will increase the frictional force. Therefore we can say that it is easier to pull the lawn roller than to push it because the normal component of force decreases when the lawn roller is pulled. Therefore, It is easier to pull a lawn roller than to push it because pulling Decreases normal reaction.

## What are the advantages of friction?

• Friction enables us to walk freely.
• It helps to support ladder against wall.
• It becomes possible to transfer one form of energy to another.
• Objects can be piled up without slipping.
• Breaks of vehicles work due to friction.
• It always resists the motion, so extra energy is required to overcome it.

## What is limiting friction?

Limiting friction is defined as the friction which is generated between the two static surfaces that come in contact with each other. … In other words, the amount of friction that can be applied between two surfaces is limited and if the forces acting on the body are made sufficiently great, the motion will occur.

## Why a horse Cannot pull?

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. … Therefore, a horse cannot pull a cart and run in empty space.

## Does a horse push or pull a wagon?

Anatomically, the horse is pushing in order to move the cart. The harness distributes the load across the horse’s breast and barrel (with a light harness), or along the base of the neck and shoulders, and across the chest (with a heavy harness. By pushing into the harness, the horse creates the required force.

## Why a horse can not pull a cart in empty space?

(a) For pulling a cart or for running, the horse pushes the earth with its feet and reaction of the earth makes it move in the forward direction. Since in empty space there is no reaction force, therefore the horse cannot run in empty space.

## What type of motion is the horse pulling a cart?

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.

## What is the motion of swings?

The movement of Swing is called oscillatory motion.

## What do you mean by motion in a straight line?

If an object moving along the straight line covers equal distances in equal intervals of time, it is said to be in uniform motion along a straight line. Fig. 3.2(b) shows the position-time graph of such a motion.
