The comprehensive equation sheet, vector mechanics rules, and fluid dynamic formulas needed to ace your university freshman mid and final exams.
Freshman General Physics (Phys 1011) is one of the most challenging common courses for first-year Ethiopian university students in natural science and engineering streams.
Key Formula Summary - **Newtonian Dynamics:** $\sum \mathbf{F} = m \mathbf{a}$, with kinetic friction $f_k = \mu_k N$. - **Work-Energy Theorem:** $W_{\text{net}} = \Delta K = \frac{1}{2}m v_f^2 - \frac{1}{2}m v_i^2$. - **Bernoulli's Principle:** $P_1 + \frac{1}{2}\rho v_1^2 + \rho g h_1 = P_2 + \frac{1}{2}\rho v_2^2 + \rho g h_2$. - **Simple Harmonic Motion (SHM):** $\omega = \sqrt{\frac{k}{m}}$, period $T = 2\pi \sqrt{\frac{m}{k}}$.
