COMPOSITION OF CONCURRENT FORCES CONSERVATION OF MECHANICAL ENERGY OBJECTIVES Purpose The purpose of this experiment is to use the force table to experimentally determine the force which balances two other forces. This result is compared with the results acquired by mathematically adding the two forces by using their components The purpose of this experiment is to demonstrate how mechanical energy is conserved, specificaly n specifically how the spring potential energy of the compressed spring (component method) and by graphically adding the forces (graphical method). er of a cart (at rest) is converted into gravitational potential energy of the cart as it reaches its highest position along an inclined track. Theory The potential energy of a spring compressed a distance x from equilibrium is given by PE,ring" ing kx', where & is the spring constant. According to Hooke's Law, the force exerted by the spring is proportional to the distance the spring is compressed or stretched, F = kx, where A is the proportionality constant. Thus the spring constant be experimentally determined by applying different forces to stretch or compress the spring different distances. When the force is plotted versus distance, the slope of the resulting straight line is equal to k. The gravitational patential energy gained by a cart as it climbs an indine is given By PEgrav " magh, where m is the mass of the cart, a is the acceleration due to gravity, and & is the vertical height the cart is raised. In terms of the distance, #, along the Fig. 1. Farce Table Assembly incline, the height is given by A = d sind. If energy is conserved, the potential energy in the compressed spring will be completely converted into gravitational potential energy.

Energy.pdf NEWTON'S SECOND LAW Objectives The purpose is to verify Newton's Second Law, F = ma. Theory According to Newton's Second Law, F = ma. F is the net force acting on the object of mass m and a is the resulting acceleration of the object. PDF For a cart of mass m, on a horizontal track with a string attached over a pulley to a mass *, (see Figure 1), the net force F on the entire system (cart and hanging mass) is the weight of hanging mass, F hat friction is negligible. According to Newton's Second Law, this not force should be equal to me, where m is the total mass that is being accelerated, which in this case is as + m . This experiment will check to see if mig is equal to (m, + m, ) when friction is ignored. To obtain the acceleration, the cart will be started from rest and the time (t) it takes for it to travel a certain distance (d) will be measured. Then since d = zar, the acceleration can be calculated using a = # (assuming that a = constant).
