Laws of Motion
... Inertia. Inertia is the tendency of an object to resist changes in its velocity. Newton’s second law of motion states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The net force is equal to the mass times the acceleration, Fnet = m *a, with units of Newtons (N). If an object is in equilibrium the acceleration will be equal to zero. If an angle is involved you must use a vector sum, and the force total in the x and y direction will be equal to zero. For example if you wanted to find the net force of a 5 kg object with and acceleration of 5.17 m/s², you would simply get, Fnet = 5 * 5.17 = 25.9 N. Here are few types of forces that we worked with. That is the normal force (Fnorm), the force of friction (Ffrict), and the force of gravity (Fgrav). The normal force is the force normal or perpendicular to the surface acting on the object. The force of friction is the force exerted by a surface as an object moves across it. The force of friction is opposite to motion. The gravitational force is the mutual force of attraction between any objects in the Uni...
