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] 21 Page HPSG041 JULY/AUGUST EXAMINATION 2021 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] 3.6. Angular momentum plays a key role in dealing with central forces because it is constant over time. Suppose the angular momentum, L, of a point mass is given by: L = r xp By nature of the cross product, what two properties does L have? [2] 3.7. Show that: If a particle is subject to a central force only, then its angular momentum is conservedi.e. If Vt)= V(r), then d/dt = 0. [5]
