Physics Equations
| Question | Answer |
|---|---|
| ∆x = x-xi | Displacement |
| s = d/t | Average Speed |
| v = ∆x/∆t (or) x = x-xi/t-ti | Average velocity |
| v = v+vi/2 | Average Velocity |
| a = ∆v/∆t (or) a = v-vi/t-ti | Average acceleration |
| f_net = ma | Net force (sum of all forces acting on that object) |
| w = mg | weight |
| f_g = mg | Force of gravity |
| f~. = .~f | Newtons third law |
| v = vi +at | FOR KINEMATIC PROBLEMS |
| x = xi+1⁄2(v+vi)t | FOR KINEMATIC PROBLEMS |
| x = xi+vi(t)+1⁄2at^2 | FOR KINEMATIC PROBLEMS |
| v^2 = vi^2+2a(x-xi) | FOR KINEMATIC PROBLEMS |
| v = vi+gt | FOR KINEMATIC FREES FALL PROBLEMS |
| y = yi+1⁄2(v=vi)t | FOR KINEMATIC FREES FALL PROBLEMS |
| y = yi+vi(t)+1⁄2gt^2 | FOR KINEMATIC FREES FALL PROBLEMS |
| v^2 = 2g(y-yi) | FOR KINEMATIC FREES FALL PROBLEMS |
