3.1. By definition, what is meant by central force ? [2] 3.2. What is the equivalent definition in terms of potential energy of the system?[2 3.3. Give the mathematical relation that links the force in view of the two definitions. [2] 3.4. Give three examples of central forces [3] 3.5. State two properties that have a particle subjected only to a central force.[2] 2 Page HPSG041 JULY / AUGUST EXAMINATION 2021 3.6. Angular momentum plays a key role in dealing with central forces because it is constant over time. Suppose the angular momentum, 7, of a point mass is given by: I = XP 3.7. By nature of the cross product, what two properties does I have? [2] Show that: If a particle is subject to a central force only, then its angular momentum is conserved i.e. If V(r) = V(r), then du/dt = 0. [5]
