Read each question carefully and answer to the best of your ability. Show all your work for calculation questions.
1. Which of the following best describes speed?
The rate at which an object changes its position in a specific direction.
The total distance covered divided by the total time taken.
The change in velocity over time.
The amount of matter in an object.
2. An object moving at a constant speed in a straight line has:
Increasing velocity
Decreasing velocity
Constant velocity
Zero displacement
3. The unit for speed in the International System of Units (SI) is .
4. is a vector quantity, meaning it has both magnitude and direction.
5. A change in an object's velocity over time is known as .
6. Distance is a scalar quantity.
True
False
7. An object can have a constant speed but still be accelerating.
True
False
8. Describe the motion of the object shown in the distance-time graph above between 2 seconds and 5 seconds.
9. A car's speedometer measures its instantaneous speed. Explain the difference between instantaneous speed and average speed.
10. A runner completes a 400-meter race in 50 seconds. Calculate the runner's average speed. Show your work.
11. A car accelerates from rest to 60 km/h in 5 seconds. Calculate the car's acceleration in km/h/s. Show your work.
