Question
Which of the following is called the position-velocity relation?
Hint:
The third equation of motion is the relationship between final velocity 'V', initial velocity 'u', acceleration 'a', and distance traveled 's'.
The correct answer is: v2 = u2 + 2as
v2 = u2 + 2as is called the position-velocity relation.
Where,
v = final velocity
u = initial velocity
s = distance traveled
a = acceleration.
