Sample Questions

1multiple correct

Which of the following are vector quantities? (Select all correct answers)

Show answer

Displacement, Velocity, Acceleration

Displacement, velocity, and acceleration are vector quantities as they have both magnitude and direction. Speed, distance, and time are scalar quantities with only magnitude.

2multiple choice

Speed is 36 km/h. Convert this to m/s:

Show answer

10 m/s

To convert km/h to m/s, multiply by 5/18. So 36 km/h = 36 × (5/18) = 10 m/s. Alternatively, 36 km/h = (36 × 1000)/(60 × 60) = 36000/3600 = 10 m/s.

3multiple choice

A car travels 200 km in 4 hours. What is its average speed?

Show answer

50 km/h

Average speed = Total distance / Total time = 200 km / 4 h = 50 km/h. This is the basic formula for calculating average speed.

4multiple choice

The slope of distance-time graph gives:

Show answer

Speed

The slope of distance-time graph represents the rate of change of distance with time, which is speed. Speed = distance/time, so slope = rise/run = distance/time = speed.
