Newton's 2nd Law of Motion

Newton's second law come into play when dealing objects that have forces which are not balanced. The acceleration of the object is dependent upon two variables: the net force and the mass. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. We had to do a Newton's 2nd Law lab in physics class. We were given a car on a frictionless track tied to a weight on a pulley system. We changed the mass of the cart and the weight of the pulley to see for ourselves exactly how acceleration is affected by force and mass.
