Physics of Dog Mushing :: sport Physics Dogs Dog Racing

Acceleration/Velocity Acceleration and velocity are mostly dependent on the number of dogs, the lineament of the dogs, and how well the dogs consecrate been trained, but it also can depend on friction and inertia. The lager piling an object has the the to a greater extent encumbrance it has and the more inertia it has. Weight effects quickening by increasing friction. Friction is f = N where is the coefficient of friction, N is the normal thread, and f is friction. The normal forces is equal to mass times gravity as meating no other downward forces are applied. Therefore the more weight in both ridege gear and musher the dogs have to haul the lower the velocity and the slower the acceleration will be due to friction between the runners and the ground. Inertia effects acceleration because inertia is the angle of dip of objects to ether stay at rest or stay in motion. In this case since the point is to move we are more concerned to the highest degree s taying at rest. When starting the dogs have to pull harder to get the sled moving then they do to keep it moving to both repress the effects of inertia and to change the fiction from static friction to kinetic friction.Force/WorkForce is necessary to start all motion, and in the charge of friction force is needed to maintain a constant velocity. In mushing a vast majority of the force comes from the dogs, and depending on the musher as a trivial amount to no force comes from the musher (assuming flat terrain).Mathematically F = ma where F is force, m is mass, and a is acceleration. this tells us that if the velocity is constant then the sum of the forces equals 0(F = 0). this doesnt mean the dogs arent consecrateing any(prenominal) force it just means that they are only applying enough force to over come any friction that might be resting the forward motion.The dogs apply this force by pulling on the tug lines which leads to a gangline which is attached to the sled. some musher s place a shock absorber between the sled and the gangline to both fill-in jolts from the dogs accelerating from a stop and to reduce the jolt on the dogs from large bumps in the trails.WorkThe dogs are only doing work when they are accelerating because W = Fd where W is work, F is force, and d is distance.Physics of Dog Mushing sport Physics Dogs Dog RacingAcceleration/Velocity Acceleration and velocity are mostly dependent on the number of dogs, the quality of the dogs, and how well the dogs have been trained, but it also can depend on friction and inertia.

Inertia effects acceleration because inertia is the tendency of objects to ether stay at rest or stay in motion. In this case since the point is to move we are more concerned about staying at rest. When starting the dogs have to pull harder to get the sled moving then they do to keep it moving to both overcome the effects of inertia and to change the fiction from static friction to kinetic friction.Force/WorkForce is necessary to start all motion, and in the presence of friction force is needed to maintain a constant velocity. In mushing a vast majority of the force comes from the dogs, and depending on the musher as a small amount to no force comes from the musher (assuming flat terrain).Mathematically F = ma where F is force, m is mass, and a is acceleration. this tells us that if the velocity is constant then the sum of the forces equals 0(F = 0). this doesnt mean the dogs arent applying any force it just means that they are only applying enough force to over come any friction that might be resting the forward motion.The dogs apply this force by pulling on the tug lines which leads to a gangline which is attached to the sled. some mushers place a shock absorber between the sled and the gangline to both ease jolts from the dogs accelerating from a stop and to reduce the jolt on the dogs from large bumps in the trails.WorkThe dogs are only doing work when they are accelerating because W = Fd where W is work, F is force, and d is distance.
