Problem
1. a In the context of oscillations, state what is meant by damping. 2. b Distinguish between free and driven oscillations.Intuitive explanation
Damping is the gradual loss of mechanical energy from an oscillating system due to resistive forces like friction or air resistance—it's why a real pendulum eventually stops swinging. Free oscillations occur when a system oscillates at its natural frequency with no external force after an initial push, while driven oscillations are sustained by a periodic external force that can push the system at any frequency you choose, even making it oscillate faster or slower than it naturally wants to.
