Question 1
What is displacement?
- AThe total length of the path travelled
- BThe shortest distance from initial to final position with direction
- CThe total time taken
- DThe rate of change of speed
Show answerHide answer
Answer: B
Displacement is the change in position from the initial point to the final point with direction.
Question 2
Which quantity is a scalar?
- ADisplacement
- BVelocity
- CDistance
- DAcceleration
Show answerHide answer
Answer: C
Distance has magnitude only and is a scalar quantity.
Question 3
Which quantity is a vector?
- ADistance
- BSpeed
- CTime
- DDisplacement
Show answerHide answer
Answer: D
Displacement has magnitude and direction.
Question 4
When can the magnitude of displacement equal the distance travelled?
- AWhen the object follows a straight path without reversing direction
- BWhen the object completes a full circular trip
- CWhen the object returns to its starting point
- DIn every journey
Show answerHide answer
Answer: A
For straight-line motion without changing direction the distance equals the displacement magnitude.
