Please mark me as brainlliest

Answer 2

Explanation:

hlo mate....

1.speed=speed is defined as the distance travelled by a body during ap particular time

Si unit =m/s.

.

2.Velocity= it is defined as the displacement travelled by a body in given interval of time..

Si

unit =m/s.

3. Acceleration = it is defined as the change in velocity in given time period.

Si unit =m/s^2

I have already given their formulas....
