In the last explainer we talked about the graphical representation of motion and i told you all about different graphs. In this explainer i will explain the 3 equations of motions on which numericals come in exam.
1st equation of motion
v = u + at (v-final velocity, u-initial velocity, a-acceleration, time)
2nd equation of motion
s = ut + 1/2 a(t sq.)
3rd equation of motion
v sq. = u sq. + 2as
On these equations only, in the exam it can be asked about final velocity, initial velocity, acceleration, time, distance and you have to use these equations for it.
