Force, momentum and energy offer complementary ways to describe motion. The useful method depends on the system and constraints.
⚡ Quick Win
Start with a free-body diagram, then decide whether to use force equations, momentum conservation or an energy balance.

Simple harmonic motion describes local oscillation; a wave transfers a disturbance through space. Their frequency, phase and energy relationships need separate interpretation.
