The Atwood Machine Bijaya Singh Thapa Abstract: Newton’s First Law of motion described what happens when the net force on a body is zero; if the body is at rest it will remain at rest, and if the body is already in motion it will continue to move with constant speed in a straight line. Newton’s Second Law of motion describes what happens if the net force is not zero-the body will accelerate in the direction of the force, the acceleration being directed proportional to the force and inversely proportional to he mass of the body, F = ma. If the acceleration is constant, the motion is said to be uniformly accelerated. Thus constant force will produce an uniformly accelerated motion. After experiment I got acc. from experiment and another value of acc. from using Newton’s second law. And the percent error in this experiment is -2 to 26%. From Newton’s Second Law for the system takes the form m d g - m u g - f = (m...
