What kinematic decay and drag means in Mathematics A-Level, as defined for WJEC.
Definition of kinematic decay and drag
Check what you remember
Read the wording for your board, then hide it and explain kinematic decay and drag in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Solving m dv/dt = −kv produces velocity decay v(t) = v₀ e^(−kt/m), showing that velocity approaches zero asymptotically as t → ∞.
