- Learn and try: The kinematic equations (article) | Khan Academy
Learn what the kinematic equations are and how you can use them to analyze scenarios involving constant acceleration
- Choosing kinematic equations (video) | Khan Academy
Kinematic equations help solve for an unknown in a problem when an object has either a constant velocity or constant acceleration This video will help you choose which kinematic equations you should use, given the type of problem you're working through
- Isolating quantities | Lesson (article) | Khan Academy
What are isolating quantities problems? Many real-world scenarios can be described using equations and formulas with multiple variables For example, the formula for the area, A , of a rectangle with length ℓ and width w is A = ℓ w In this form, area (A ) is isolated: it is alone on one side of the equation
