Just like Equation (1), Equation (2) reduces to the standard form of Newton’s second law when the system’s mass is constant. However, in addition to that, and just like its constant-mass counterpart, Equation (2) has on the left-hand side has Equation (1) as a special case when can be applied directly to variable mass problems.
You are confused about what the variables mean in Newton's second law. Newton's second law is $$\mathbf F_ {net}=m\mathbf a$$ What this means is that a net force (the sum of all forces acting on an object) produces an acceleration. This acceleration is determined by how strong the force is as well as the mass of the object. What Newton's second law does not mean is that if an object has an ...
The discussion centers around the quest for a clever or alternative name for Newton's Second Law, similar to how Newton's First Law is referred to as the "law of inertia." Participants explore various suggestions and perspectives on naming conventions in physics, touching on the implications of terminology in learning and communication within the scientific community. Some participants express ...
9 You can only apply Newton's second law to closed systems. But, since you are applying second law to a open system, you are getting contradictory results. The correct procedure for solving variable mass system, is by calculating the change in momentum and then equating it to
How do you define lagrangian at first place in form of kinetic and potential energy. Newton's second law is axiomatic and which came from definition of inertia or state of motion.
