Question

all formulas from chapter laws of motion for class 9 (PHYSICS)​

Answer 1

Answer:

Newton's 2nd Law

F=ma

Newton's 3rd Law

\vec{F_{AB}}=-\vec{F_{BA}}

Linear Momentum

\overrightarrow{P}=M\times\vec V

Impulse=\vec{I}=\int_{t_{1}}^{t_{2}}\vec{F}\cdot dt

Impulse-Momentum Theorem-

\int_{t_{1}}^{t_{2}}\vec{F}dt=\int_{p_{1}}^{p_{2}}\vec{dp}

Centripetal Force= F=m\omega ^2r

Kinetic friction force =f_{K}=\mu_{K} R

Limiting Friction force= f_{l}=\mu_{s}R
