Question

Distinguish between speed & velocity
Define acceleration. Write its SI unit​

Answer 1

Explanation:

speed has magnitude and direction

velocity has only magnitude

the rate of change of velocity is called acceleration SI unit is m/ s^2

hope it helps u

follow me....

Answer 2

Explanation:

◾Speed :-

➡ It is a Scalar Quantity..

➡It is the rate at which an object covers distance..

➡ The average speed is the distance per time ratio ....

◾Velocity :-

➡ It is a Vector Quantity....

➡ It is the rate where position changes...

➡ It is direction aware...

◾Acceleration :-

➡ It is the rate of change of Velocity...

➡ It means speed is changing but not always ...

➡ When an object moves in a circular path at a constant speed ,,it is still accelerating ,,because the direction of it's velot is changing...

◾ SI Unit :-

➡ Speed :- meter/second (m/s)

➡ Velocity :- meter/second (m/s)

➡Acceleration :- meter/second² (m/s²)
