Question

Definition of velocity , density or acceleration

Answer 1

hey buddy !! here's your answer...

➡️velocity - it is the rate of change of distance with time . it's a vector quantity having both direction and magnitude. it tells how fast a body moves .
unit - m/s

➡️density - it is the measure of mass of a matter to its volume .
unit - kg / m³

➡️acceleration - rate of change of velocity per unit time . it is also vector quantity.
unit - m/s²

hope it helps !! ❤️✌️

Answer 2

velocity :
velocity is the displacement per time.
density :
mass and time

acceleration : the acceleration of an object is the change in velocity per unit time
