Question

list all the formula of class 9 physics

Answer 1

Hlo friend.. Cutiepie Here..

Here is ur answer :

Ch 8 Motion.

Three equation of motion.

1. Final velocity = Initial velocity + acceleration × time.

v = u + at

2. Distance = Initial velocity × time + 1/2 × acceleration × ( time) ².

s = ut + 1/2 at²

3. ( Final velocity)² - ( initial velocity) ² = 2 × acceleration × distance.

v² - u² = 2as.

Ch 9 Force and laws of motion

1. Momentum = mass × velocity

P = mv

2. Force = mass × acceleration.

F = ma.

Ch 10 Gravitation


1. Gravitational force = G m m / R²
¹ ²

2. Weight = mass × acceleration due to the gravity.

F = mg

When body is free falling.

I) v = u + gt

II) h = ut + 1/2 gt²

III) v² - u² = 2gh.

Ch 11 Work and energy

1. Work = force × displacement

W = Fs

2. Energy consumed = work done

3. Potential energy = mass × acceleration due to gravity × height.

P. E. = mgh

4. Kinetic energy = 1/2 × mass × ( velocity)²

K. E. = 1/2 mv².
