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).
Problems will involve motion in a straight line with constant acceleration in scalar form, where the forces act either parallel or perpendicular to the motion.
Problems may involve motion in a straight line with constant acceleration in vector form, where the forces are given in form or as column vectors.
Extend to problems where forces need to be resolved, e.g. a particle moving on an inclined plane.
