About


This site is not meant to be a learning center rather a review site. It assumes you have a surface level knowledge of every subject covered. The goal is not to replace Ap Classroom or teacher based instruction, but rather to supplement it.

Built of off my AP physics class, Khan Academy, various websites, and the AP Physics 1 guided learning plan.

Unit One | Kinematics


Kinematics:

Deal with pure motion. Usually from the beginning to the end of the described motion. Usually two types, motion with constant Velocity or motion with constant Acceleration

Vector and Scalar:

The Big Four Equations

  1. $$V_f^2 = V_i^2 + 2*A*D$$
  2. $$D = V_i * T + \frac{1}{2}A * T^2$$
  3. $$V_f = V_i + A * T$$
  4. $$D = \frac{V_i + V_f}{2} * T$$

Now given a position time graph. You can find the slope to get the velocity

    Inertial Mass vs Gravitational Mass

  • Inertia Equations:
    1. Hoop about a symmetric axis
    2. $$I = M*R^2$$
    3. Solid cylinder
    4. $$I = \frac{1}{2}M*R^2$$
    5. Solid Sphere
    6. $$I= \frac{2}{5}M*R^2$$
    7. Rod about a center
    8. $$I = \frac{1}{12}M*L^2$$
    9. Solid Cylinder, central diameter
    10. $$I = \frac{1}{4}M*R^2 + \frac{1}{12}M*L^2$$
    11. Hoop about a diameter
    12. $$I = \frac{1}{2}M*R^2$$
    13. Thin spherical shell
    14. $$I = \frac{2}{3}M*R^2$$
    15. Rod about an end
    16. $$I = \frac{1}{3}M*L^2$$
    17. Integral Formula
    18. $$I_p = \sum_{i=1}^N *M_i * R_i^2$$
