When a tractor is pulling a sled there is the mass and gravity of both the tractor and sled slowing it down. There is also tension in the rope pulling the sled. whenever physics is involved to solve a force there is usually a frictional force acting on the objects. The formula to use is F=ma. The total mass is the mass of the objects put together and the total force is the force that the tractor is pulling at minus mg (mass x gravity) and minus the frictional force. The tension (T) is calculated using the formula T=W+ma (W=mgh), using only the mass of the sled.

∙ 14y agoGarden tractor pulling is an event where people hook up tracters to sleds filled with weight and then the tractors start to pull the sled and see how far the can go before spinning out.
The law of motion that relates to a dog pulling a sled is Newton's third law of motion. It states that for every action, there is an equal and opposite reaction. In this case, as the dog exerts force on the sled by pulling it forward, there is an equal and opposite force exerted by the sled on the dog, enabling the forward movement of the sled.

Pulling a sled tends to lif the sled and decrease friction thus making less difficult. Pushing does the opposite.
Pulling a sled across a sidewalk because rougher surfaces have more friction.
