The 20 questions

  1. What is the scientific definition of velocity?

    • Speed without direction
    • Acceleration over time
    • Speed with direction
    • Distance over time

  2. What type of physical quantity is velocity?

    • Constant
    • Scalar
    • Base
    • Vector

  3. Which pair contains only scalar quantities?

    • Distance and velocity
    • Displacement and speed
    • Velocity and displacement
    • Distance and speed

  4. Two cars travel at the same speed, one north and one south. What is different?

    • Mass
    • Kinetic energy
    • Velocity
    • Speed

  5. A car travels at 20 m/s north. Its velocity is:

    • 20 m/s
    • 20 m north
    • 20 m/s squared north
    • 20 m/s north

  6. A train goes from 10 m/s east to 10 m/s west. What has changed?

    • Mass
    • Distance
    • Velocity
    • Speed

  7. What happens to a satellite moving in a circle at constant speed?

    • Neither changes
    • Both remain constant
    • Speed changes
    • Velocity changes

  8. Why does circular motion at constant speed involve changing velocity?

    • Speed increases constantly
    • Direction changes continuously
    • Distance decreases steadily
    • Magnitude is zero

  9. A runner completes a 400 m lap in 80 s and ends at the start. Her average velocity is:

    • 5 m/s
    • 0 m/s
    • 5 m/s east
    • 10 m/s

  10. A bird flying due south at 12 m/s has a velocity of:

    • 12 m due south
    • 12 m/s due south
    • 12 m/s squared due south
    • 12 m/s

  11. What two properties are needed to fully specify a velocity?

    • Magnitude and direction
    • Speed and time
    • Force and acceleration
    • Distance and mass

  12. Which of these is a scalar quantity?

    • Mass
    • Acceleration
    • Velocity
    • Force

  13. (Harder) An object goes 300 m east then 400 m north in 100 s. The magnitude of its average velocity is:

    • 1 m/s
    • 5 m/s
    • 7 m/s
    • 3.5 m/s

  14. (Harder) An object moves 12 m east in 3 s and then 12 m west in 3 s. Its average velocity is:

    • 0 m/s
    • 4 m/s east
    • 8 m/s west
    • 4 m/s

  15. What key property distinguishes velocity from speed?

    • Direction
    • Time
    • Mass
    • Magnitude

  16. What physical property does a standard vehicle speedometer fail to show?

    • Current speed
    • Elapsed time
    • Direction of travel
    • Total distance

  17. A dog runs 4 m/s in a straight line, turns, and runs back at 4 m/s. Which quantity stays constant?

    • Its velocity
    • Its speed
    • Its direction
    • Its displacement

  18. What happens to the velocity of an object whirled in a circle at constant speed?

    • Speed increases constantly
    • Magnitude becomes zero
    • Direction keeps changing
    • Values remain identical

  19. A plane flies 500 km north in 1 hour and then 500 km south in 1 hour. Its average velocity is:

    • 1000 km/h
    • 0 km/h
    • 500 km/h
    • 500 km/h north

  20. Which changes will always alter an object's velocity?

    • Energy or power
    • Mass or weight
    • Temperature or pressure
    • Speed or direction
