motion of an object. Understand how relative speed depends on the direction of movement (in context of two cars travelling on a straight road). ||  ||   || • some quantities, (e.g. mass, time), direction is not relevant (scalar) • some quantities, (e.g. force, velocity, acceleration) direction is important (vector). Calculate the vector sum from vector diagrams of parallel vectors (limited to force and velocity in thesame or opposite directions). ||  ||   ||
