Question
A car is moving at a speed of 5 m/s in the same direction throughout its motion. Which of the following is true about its motion?
- Speed = magnitude of velocity
- Distance covered = displacement
- Acceleration = 0
- All of the above
Hint:
All of the above
The correct answer is: All of the above
If a car is moving at a speed of 5 m/s in the same direction throughout its motion then acceleration will be zero, distance will equal to displacement, and speed will be equal to the magnitude of velocity.
Justification:
As there is no change in velocity (uniform speed) the acceleration will be zero
If the car is moving in a straight line then the distance will be equal to displacement.
Also, the car is moving with constant speed and no acceleration, therefore, the speed will be equal to the magnitude of velocity.
