What projectile trajectories means in Mathematics A-Level, as defined for WJEC.
Definition of projectile trajectories
Check what you remember
Read the wording for your board, then hide it and explain projectile trajectories in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
For projectile motion under gravity, x(t) = (V cos θ)t and y(t) = (V sin θ)t − ½gt² parameterise the flight path, with the parameter domain restricted to 0 ≤ t ≤ T.
