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 …
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 …
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 …
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.
Acceleration vs. time graphs (article) | Khan Academy
Learn how to interpret the motion of an object represented on an acceleration vs. time graph.
Angular motion variables (video) | Khan Academy
And the angular acceleration represents the rate at which an object is changing its angular velocity, so if an object rotates at a constant rate, there is zero angular acceleration, but …
Acceleration (video) | Motion | Khan Academy
Acceleration is change in velocity. If an object's speed and/or direction is changing, it is accelerating. If an object is speeding up, its velocity and acceleration are in the same direction. …
The kinematic equations (article) | Khan Academy
Learn what the kinematic equations are and how you can use them to analyze scenarios involving constant acceleration.
Freefall review (article) | Khan Academy
Review the key concepts and skills for acceleration due to gravity, including analyzing motion of objects in freefall.
Acceleration (video) | Khan Academy
If velocity and acceleration point the same direction, the object is speeding up. If velocity and acceleration point opposite directions, the object is slowing down.
