There are three equations of motion:-
Explanation:-
This equation is used to find the final velocity of a body or latest velocity of body or current velocity of body. This equation is known ass first equation of body.
Whenever a body starts to move it have some initial velocity and when after some interval of time t it have some change in velocity, after which its velocity becomes So above equation is for final velocity. Now see its derivation.
Change in velocity ∆v is equal to,
(2)
This is equation
is used to find the distance covered by a body having initial velocity Vi and
after time t.
Consider a
car moving with initial velocity Vi and final velocity Vf, then it would have
average velocity will be,
(3)
In this equation there is distance , acceleration, final velocity and initial velocity are related.
We could find one, if we know other.
According to first equation of motion,
