Question 1. Select the quantity that has changed--velocity or speed-- for a car that travels north at 88 km/h and then turns east while continuing to move at 88km/h.
Question 2. Infer how distance and speed in the motions of clock parts are used to measure time.
Question 3. How can you use a speedometer and a clock to tell how far you've traveled in a car if the car's odometer is not working.
Question 4. Apply the concept of momentum to compare a slow-moving train and a high-speed bullet.
Question 5. Indicate which of the following has greater momentum: a 500 kg car moving at 64km/h, a 250 kg cart moving at 128 km/h, or a 1000 kg truck moving at 32 km/h.
Question 6. Infer what you can say about the velocity of a car that is moving with a constant momentum.
