Physics formulas for Class $9$ are one of the most effective tools to prepare Physics. Physics is one of the most important subjects in Class $9$. Students must understand the concepts of the subject properly in order to score well in their exams. Class $9$ physics is filled with numerous interesting topics that deal with the natural world and the properties of matter and energy. The physics formulas for class $9$ are given here to guide students to understand the concepts effectively. Students of the $9$th standard are advised to learn the physics formula lists thoroughly to build a strong grip on the subject. Without having a grip on the formulas, students will face lots of difficulties solving problems on topics like optics, electric current, electromagnetism, laws of motion, electromagnetic radiation, etc.

1. Speed$=$ distance/time
2. Acceleration $=$ change in speed/time $=v-u / t$
3. Eq's o motion

$(a)$ $v=u+a t$

$(b)$ $s=u t+1 / 2 a^{2}$

$(c)$ $v^{2}-u^{2}+2 a s$

Forces

1. Force, $F=m a$
2. Momentum, $\mathrm{P}=\mathrm{MV}$
3. Conservation of momentum, $\mathrm{m}_{\underline{1}} \underline{\mathrm{u}}_{\underline{1}}+\mathrm{m}_{\underline{2}} \underline{\mathrm{v}}_{\underline{2}}$

Final Answer:-

The correct answer is Physics formulas for Class $9$ are one of the most effective tools to prepare Physics.
