Acceleration?
The rate at which speed changes, and the direction in which it changes.
Acceleration is the rate that speed changes.
Acceleration
Acceleration is the rate at which speed changes, at least scalarly.
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
Speed is the rate at which an object moves, while velocity is the rate at which an object changes its position. Acceleration, on the other hand, is the rate at which an object changes its velocity. Speed and velocity are scalar quantities, while acceleration is a vector quantity.
Acceleration is a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
The rate at which speed changes is acceleration, which is the change in velocity over time. The rate at which direction changes is angular acceleration, which is the change in angular velocity over time.
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
No. It's the rate at which a object changes velocity (speed).
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
