Question

motion notes of class 9 with formulas​

Answer 1

Answer:

Motion

It is the phenomenon in which an object changes its position over a time .

Motion is mathematically described 8n term of displacement, distance, velocity, speed, acceleration, ...etc.

1. First Equation of Motion:

(Velocity-Time Relation)

            v = u +at

Where,  v = Final velocity of body

            u = Initial velocity of body

            a = Acceleration

And     t = Time

Derivation:

Using formula for acceleration:

a =v-u÷t

at=v-u

2. second equation of motion



s= ut+1/2at^2

3. third equation of motion.



v^2=u^2 +2as

I hope it help you ❣❣
