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

    Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your …

  2. Acceleration: At a glance (article) | Khan Academy

    We can describe acceleration as the change in velocity over time, and we can use the shorthand equation a = Δ v / Δ t to represent this relationship where ‘a’ is the average acceleration, ‘v’ is …

  3. Acceleration (video) | Motion | Khan Academy

    Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared …

  4. Newton's second law review (article) | Khan Academy

    The videos on Newton Second Law of Motion only showed things in their current state; how would you show something moving, for example, accelerating North at 20 Newtons and slowing down by a …

  5. Connecting motion and forces (article) | Khan Academy

    Use a simulation to investigate the effects of balanced and unbalanced forces on an object's motion. Explore how an object's acceleration is affected by the net force acting on it and its mass.

  6. Velocity vs. time graphs (article) | Khan Academy

    The slope of a velocity graph is the acceleration. Since the slope of the curve is decreasing and becoming less steep this means that the acceleration is also decreasing. It might seem …

  7. Newton's first and second laws (article) | Khan Academy

    An applied force causes acceleration. The acceleration is directly related to the force, the velocity is irrelevant. The same force will cause the same acceleration if the velocity is 0 or 1,000 m/s.

  8. Newton's second law of motion (video) | Khan Academy

    Newton's second law of motion states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleration, and objects with larger mass …

  9. Acceleration questions (practice) | Khan Academy

    An ambulance is currently traveling at 15m/s, and is accelerating with a constant acceleration of 5 m/s 2 . The ambulance is attempting to pass a car which is moving at a constant velocity of 30m/s. How far …

  10. Acceleration (video) | Khan Academy

    Acceleration is when an object's velocity is changing over time. Let's ignore the changing direction case and just focus on changing speed. An object can change speed either by speeding up or slowing …
