I would guess that the force required to move the horse is called normal force. It's the force of the ground pushing on the horse's hooves (don't know if i spelled that correctly). The force pulling the cart is..the force of the horse? I don't know the answer, but thought i'd give it a try until someone gives you a more confident and correct answer. good luck.

maanneaguila: give us your best understanding of what's happening. Forget forces for a moment. How is a horse able to move?

thanks for the idea., :D

i have here also, but not so sure if it's correct..,

the force that cause the horse to move forward is the force exerted by the hoofs/hooves and legs of the horse on the ground., it should be greater than the frictional force on the ground., :)

As a scientist, it is important to use scientific principles and equations to explain the forces acting on the horse and cart system.

(a) The force that causes the horse to move forward is the force of the horse's muscles pulling on the reins attached to the cart. This force is known as the applied force or the driving force.

(b) The force that causes the cart to move is the force of friction between the wheels of the cart and the ground. This force is known as the rolling or kinetic friction force.

In order to fully understand the forces acting on the horse and cart, we can use Newton's laws of motion. According to Newton's first law, an object will remain at rest or in motion at a constant velocity unless acted upon by an external force. In this case, the horse and cart system is initially at rest, but the applied force from the horse's muscles causes it to accelerate forward.

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the larger the applied force from the horse, the greater the acceleration of the horse and cart system. Additionally, the larger the mass of the cart, the smaller the acceleration will be.

Finally, Newton's third law states that for every action, there is an equal and opposite reaction. In this case, the applied force from the horse's muscles creates an equal and opposite reaction force from the ground, which allows the horse and cart to move forward.

In conclusion, the forces acting on the horse and cart system are the applied force from the horse's muscles and the force of friction between the wheels of the cart and the ground. By understanding these forces and applying Newton's laws of motion, we can better understand the movement of the horse and cart system.
