identify the vector quantity from the following speed, work, power, velocity
Answers
Answer:
velocity is the vector quantity in the below given list.
Explanation:
Vector quantity is the quantity which has both magnitude and direction.
In the given list only velocity has both magnitude and direction so velocity is the vector quantity.
Power is form of energy which can have direction but no magnitude so scalar quantity.
same is the case with speed.
work has distance but not displacement so scalar.
Explanation:
Velocity is a vector quantity, but power, work and speed are scalar quantities. Vectors have a magnitude as well as a direction that can be used to specify it correctly. It is generally shown by an arrow, the direction of which is the same as that of the quantity. Its length is usually proportional to the quantity’s size. So if you want to measure the volacity quantity then you can measure the speed, power and work according to their scalar quantities.
