Question

Which one is the polar vector in the given options?
This question has multiple correct options
(A). Acceleration
(B). Moment of inertia
(C). Angular momentum
(D). Velocity

Answer 1

Hint: A polar vector is a vector-like the radius vector that reverses sign when the coordinate axes are reversed. Polar vectors are the type of vector usually simply known as "vectors."

Complete step-by-step answer:
Think about a ball hurled into the air. Gravity is quickening the ball at a consistent pace of
\[g=9.8\dfrac{m}{s}\]
 At the point when the ball is voyaging upward, acceleration is the other way, and the ball eases back. At the point where the ball eases back to a velocity of \[0\dfrac{m}{s}\] gravity is as yet following up on the ball.

At that point the ball starts to move to descend because gravity is as yet following up on it, however now the movement and acceleration are in a similar way, so the ball accelerates.
Velocity is a vector quantity that alludes to "the rate at which an item changes its position."

Imagine an individual moving quickly - one stage forward and one stage back - continually coming back to the first beginning position. While this may bring about a craze of action, it would bring about a zero velocity.

 Since the individual consistently comes back to the first position, the movement could never bring about an adjustment in position.
Since velocity is characterized as the rate at which the position changes, this movement brings about zero velocity.

Note: Velocity is a vector quantity. In that capacity, velocity is bearing mindful. While assessing the velocity of an item, one must monitor heading. It would not be sufficient to state that an
the object has a velocity of\[55\text{ }\dfrac{mi}{hr}\]. One must remember course data for requests to completely portray the velocity of the item. For example, you should portray an item's velocity as being \[55\text{ }\dfrac{mi}{hr}\], east. Speed is a scalar quantity and doesn't monitor course; velocity is a vector quantity and is aware of the direction.
