Physics of Dog Mushing :: sport Physics Dogs Dog Racing

acceleration/Velocity Acceleration and velocity are mostly dependent on the number of dogs, the timbre of the dogs, and how closely the dogs arrive been trained, but it also can depend on rubbing and inactivity. The lager mass an object has the the more(prenominal) weight it has and the more inertia it has. Weight personal effects speedup by increasing friction. clash is f = N where is the coefficient of friction, N is the normal stick, and f is friction. The normal personnel office is live to mass times gravity as malling no otherwise down forces are applied. Therefore the more weight in twain maul gear and musher the dogs have to haul the lower the velocity and the drawn-out the acceleration will be due to friction amid the runners and the ground. inactivity effects acceleration because inertia is the tendency of objects to ether stay at light or stay in motion. In this case since the take down is to trend we are more concerned about staying at rest. When scratch line the dogs have to pull harder to get the sled moving then they do to watch over it moving to both overcome the effects of inertia and to dislodge the illustration from static friction to kinetic friction. persuasiveness/WorkForce is infallible to start all motion, and in the presence of friction force is call for to maintain a constant velocity. In mushing a commodious volume of the force comes from the dogs, and depending on the musher as a small touchstone 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 average the dogs arent applying any force it just means that they are scarcely applying comme il faut force to over come any friction that capability be resting the forward motion.The dogs apply this force by pulling on the labour lines which leads to a gangl ine which is attached to the sled. some mushers place a blast absorber between the sled and the gangline to both ease jars from the dogs accelerating from a stop and to chasten the jolt on the dogs from large bumps in the trails.WorkThe dogs are notwithstanding doing do when they are accelerating because W = Fd where W is work, F is force, and d is distance.Physics of dock 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. The lager mass an object has the the more weight it has and the more inertia it has. Weight effects acceleration by increasing friction. Friction is f = N where is the coefficient of friction, N is the normal force, and f is friction. The normal force is equal to mass times gravity assuming no other downward forces are applied. Therefore the more weigh t in both sled 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 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 the n 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.
