  1. What is velocity? (article) | Khan Academy

    Velocity or speed? Instantaneous or average? Keep building your physics vocabulary.

  2. Position vs. time graphs (article) | Khan Academy

    If the slope of the graph is positive (tilted up), the object had positive velocity at that time. At any time the position and velocity may both be positive, both be negative, or have different signs. …

  3. What is velocity? (article) | Khan Academy

    Your notion of velocity is probably similar to its scientific definition. You know that a large displacement in a small amount of time means a large velocity and that velocity has units of …

  4. Calculating average velocity or speed (video) | 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, …

  5. Projectile motion (article) | Kinematics | Khan Academy

    A projectile’s horizontal motion can be modeled as motion with constant velocity. We can visualize this with velocity component vectors. Return to the simulation. Under Velocity Vectors, check …

  6. Vectors in 2D (article) | Kinematics | Khan Academy

    A bird is flying with a horizontal velocity v x = 9.3 m/s and a vertical velocity v y = 8.6 m/s. Calculate the magnitude and angle, relative to the horizontal, of the bird's total velocity. Enter …

  7. The kinematic equations (article) | Khan Academy

    This equation can be derived by combining two equations for average velocity. Average velocity is defined as displacement divided by the time during which that displacement occurred:

  10. Interpreting change in speed from velocity-time graph

    Let's examine a velocity-time graph to understand an object's motion. By distinguishing between positive and negative slopes, we discern whether the object is speeding up, slowing down, or …
