- speed
- velocity
- mass
- weight

Question 2: Which of the following quantities relating to motion is not a vector?

- Speed
- Velocity
- Mass
- Weight

Question 3: A car is traveling at 50m/s, the driver uses the brakes to stop the car in 10 seconds.

Find the average acceleration of the car.

- 4 s
- 5 s
- 6 s
- 3 s

Explanation: At time = 0, speed V

Acceleration (a) = V

Question 4: Find the acceleration of a car traveling at constant speed.

- 0 m/s
^{2} - 1 m/s
^{2} - 2 m/s
^{2} - Impossible to find.

Note that the car could still have acceleration when it is traveling in circular motion because its direction is constantly changing.

Question 5: A quantity that is a measure of how the velocity of a body changes with time is called

- Speed
- velocity
- acceleration
- none
