Question

Important formula for class 9 motion

Answer 1

Answer:

Explanation:

S=ut+1/2at²

V=u+at

V²-u²=2as

Answer 2

Explanation:

there are 3 kinematic equation

2as= v^2 -u^2

v = u + at

s = 1/2ut + at^2

most important and there graphical presentation

and other one is .

uniform circular motion

2πr/t

and easy but need to be remembered

s= d/t

avg speed = total distance covered / total time taken

hope it helps u
