What is acceleration? (article) | Khan Academy
In everyday language people use the word deceleration to describe slowing down. But in physics, we use the single term acceleration to mean any change in velocity, whether it be speeding …
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 …
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 (video) | Khan Academy
Well, in physics in general, acceleration is defined as the rate of change in velocity. In other words, it's a measure of how quickly your velocity is changing, and we'll take a lot of examples …
Connecting motion and forces (article) | Khan Academy
An object's acceleration —how quickly its velocity changes—depends on the strength of the net force exerted on it. A stronger net force causes a greater acceleration if the object's mass …
Uniform circular motion and centripetal acceleration review
Review the key concepts, equations, and skills for uniform circular motion, including centripetal acceleration and the difference between linear and angular velocity.
What is weight? (article) | Laws of motion | Khan Academy
The text says that the Earth still exercises a gravitational force at the height at which the ISS orbits. Would an astronaut who jumps out of the ISS fall down to earth? And do the pods that …
Circular motion (article) | Khan Academy
The net force that acts on an object in the radial direction is sometimes referred to as centripetal force. The acceleration that it causes, also in the radial direction, is called centripetal …
Acceleration vs. time graphs (article) | Khan Academy
An acceleration vs. time graph represents the acceleration of an object as a function of time. For example, if you read the y -value of the graph below at a particular time (in seconds), you will …
Acceleration (video) | 4th quarter: Physics | Khan Academy
Let's explore what acceleration is and how we calculate it. Created by Mahesh Shenoy.
