The kinematic equations (article) | Khan Academy
Learn what the kinematic equations are and how you can use them to analyze scenarios involving constant acceleration.
What is velocity? (article) | Khan Academy
You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, such as miles per hour or kilometers per hour.
Calculating average velocity or speed - Khan Academy
Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) …
