| For a system consisting of a single object with a net external force applied, qualitatively and quantitatively predict changes in its linear momentum using the impulsemomentum theorem and in its translational kinetic energy using the work-energy theorem. (PII.1.1)
Determine the individual and total linear momentum for a two-body system before and after an interaction (e.g. collision or separation) between the two objects and show that the total linear momentum of the system remains constant when no external force is applied consistent with Newton’s third law. (PI.5.4) Demonstrate that when two objects interact through a collision or separation that both the force experienced by each object and change in linear momentum of each object are equal and opposite, and as the mass of an object increases, the change in velocity of that object decreases. (PI.5.3) |
For a system consisting of two objects moving in two dimensions with no net external forces applied, apply the principles of conservation of linear momentum and of mechanical energy to quantitatively predict changes in the linear momentum, velocity, and kinetic energy after the interaction between the two objects.
