Velocity is
- a. the distance traveled per unit of time
- b. the same as speed
- c. direction of travel and distance traveled per unit of time
- d. only the direction of travel
Choose the correct option from the given options.
Answer to Problem 1RQ
The correct option is “
Explanation of Solution
Given data:
From the given data, it is required to define the term velocity.
Formula used:
Write the expression for the velocity of an object as follows.
Here,
Description:
The velocity is a vector parameter and it has both magnitude (quantity) and direction. From equation (1), the object’s velocity is stated as the distance travelled by an object per unit time in a particular direction.
Speed is a scalar parameter and it has only quantity (magnitude). Speed is stated as the distance travelled by the object per unit time irrespective of the direction.
Therefore, from the given options, the option c is an adequate option.
Since, the option a describes about the speed of the object and it does not describes the object’s velocity, the option a is the incorrect answer.
Since, the speed and velocity are different parameters, option b is the incorrect answer.
Since, the velocity not only describes about the direction (describes both quantity and travel’s direction), option d is the incorrect answer.
Conclusion:
Hence, the correct option is “
