Question

class 9 motion all formulas ​

Answer 1

Answer:

average speed= total distance/ total time

v= s/t (velocity= distance/time)

a=v-u/t ( acceleration= final velocity - initial velocity / time )

p=m/v ( momentum= mass/ velocity)

Newton law of motion:

kinetic energy = 1/2mass ×velocity 2

E is energy

Ek = 1/2mv2

Ep=mgh ( potential energy= mass× gravitational acceleration×height)

p=w/t and E/t

power= work done / time

and power= energy changes/ time

only 75% formula of formula I have written in this.
