Displacement
- a. can be interchanged with direction.
- b. is a measurement of volume.
- c. can be described only with a number.
- d. is the net distance an object travels, showing direction and distance.
Find the correct option.
Answer to Problem 1RQ
The correct option is “d. is the net distance an object travels, showing direction and distance”.
Explanation of Solution
Description:
Displacement is not a scalar, rather a vector quantity. Therefore, it has both magnitude and direction. The displacement can also have a negative magnitude and zero magnitude as well. Hence, it cannot be swapped with direction and cannot be defined only with a number.
The displacement cannot be always calculated using the scalar or the arithmetic addition. To calculate the displacement, vector addition is required.
Therefore, “displacement is the net distance an object travels that shows both direction and distance”.
Therefore,‘d’ is the correct option and other options are wrong.
Conclusion:
Hence, the correct option is “d”.
