30 multiple-choice questions in College Board style covering all 5 topics of Unit 1. Each question has four choices and a full explanation of why each option is right or wrong. Use g = 10 m/s² for calculations.
Sketch a quick diagram. Even a simple stick figure or arrow can save you from sign errors and direction mistakes.
Define your positive direction first. Pick one direction as positive and stick with it. Up = positive? Then a falling object has negative velocity and negative acceleration.
Check units. If you end up with wrong units, you made an algebra error. Velocity should be m/s; acceleration should be m/s².
Read every explanation. Even when you get a question right, the explanation often teaches a subtle distinction you'll see again.
