Expert Answer:

Average acceleration  begin mathsize 14px style top enclose a end style = ( vf - vi ) / Δt
 
where vi is initial velocity at time t = tand vf is final velocity at time t = toΔt .
 
 
Instantaneous acceleration :-
 
when a body changes its velocity from v to (v+Δv) in a time Δt ,
 
then instantaneous acceleration is defined as
 
begin mathsize 14px style a space equals space limit as increment t rightwards arrow 0 of space fraction numerator increment v over denominator increment t end fraction end style
