Net Force: Definition, Equation, How to Calculate Sciencing

WebBecause external forces are capable of changing the total mechanical energy of an object, they are sometimes referred to as nonconservative forces. When the only type of force doing net work upon an object is an internal force (for example, gravitational and spring forces), the total mechanical energy (KE + PE) of that object remains constant. WebDec 28, 2024 · The net force is the vector sum of all forces acting (pushing or pulling) on an object. When determining the net force, it is useful to draw a free-body diagram showing all of the forces. Once found, the net force can be set equal to the product of mass and acceleration via Newton's second law.
