Learning standards covered
R2General Certificate of Education Advanced Level (UK A-Level) · Maths · 11th Grade[Understand and use Newton’s second law for motion in a straight line (restricted to forces in two perpendicular directions or simple cases of forces given as 2-D vectors)]; extend to situations where forces need to be resolved (restricted to 2 dimensions)
Open Global Standard:OGM.13.MEC.4
R3General Certificate of Education Advanced Level (UK A-Level) · Maths · 11th Grade[Understand and use weight and motion in a straight line under gravity; gravitational acceleration, g, and its value in S.I. units to varying degrees of accuracy] [(The inverse square law for gravitation is not required and g may be assumed to be constant, but students should be aware that g is not a universal constant but depends on location)]
