By the end
- 01Convert velocities between inertial reference frames along a line and explain why acceleration is the same in all of them
- 02Resolve a vector into perpendicular components and recombine them into a magnitude and direction
- 03Solve projectile problems as two independent one-dimensional motions sharing a clock
