Define
Vector quantity
Velocity
Displacement
(I am in class 9)​

Answer 1

Answer:

1) vector 2) velocity 3) displacement

Explanation:

1) It is has both magnitude and direction. or u can say that it is a quantity that requires direction.

2) Velocity is the speed of an object moving in a definite direction. The SI unit of velocity is also metre per second. Velocity is a vector quantity; it has both magnitude and direction.

3) Displacement is defined to be the change in position of an object. it is a vector quantity as it requires direction.

Answer 2

Answer:

Vector quantity - It is a physical quantity that requires both magnitude and direction.

In easy language asa physical quantity jisme dono yani ki magnitude ( koi numerical value of speed, distance, time, acceleration,force and etc) aur direction ho.

Velocity - It is the speed.of an body in given direction.

Yani ki speed with direction. And aap speed ko velocity bhi bol sakte ho agar ye kisi straight line me hai toh. Prr difference bhi hai .

Displacement - Shortest length from initial and final position.

Yani initial position (ur first place form where u start moving) to final position (last position) ke beach ka distance.

Explanation:

This is totally new concept for u dear I know because when I was in 9th I found same .

I have written the meaning with hindi so u understand and if don't want them then ignore.

Hope it helps you (◕ᴗ◕✿)
