Under what conditions can a body travel a certain distance and yet its resultant displacement be zero ?
The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero ? Give reason for your answer.
Explain the following concept in your own words with everyday examples:
Distance
The shortest distance between two places is ______.
Assertion: Displacement of a body may be zero when distance travelled by it is not zero.
Reason: The displacement is the shortest distance between initial and final position.
Four cars A, B, C, and D are moving on a levelled road. Their distance versus time graphs are shown in Fig. 8.2. Choose the correct statement.
The displacement is zero when the initial and final positions are ______.
Give some examples for vector quantity.
Slope of a velocity-time graph gives
Assertion: If the displacement of the body is zero, the distance covered by it may not be zero.
Reason: Displacement is a vector & distance is a scalar quantity.
