Acceleration is the rate of change of velocity (not speed).
Acceleration is the rate of change of velocity over time. Velocity is defined by speed and direction. A satellite orbiting the earth at a constant speed is still accelerating because gravity is making it travel in a circle (or ellipse) and consequently its direction and therefore its velocity is constantly changing.
Speed is a scalar quantity that represents the rate at which an object is moving, while acceleration is a vector quantity that represents the rate of change of an object's velocity. Acceleration can affect the speed of an object by either increasing or decreasing it, depending on whether the acceleration is in the same direction as the object's motion or in the opposite direction. In general, the greater the acceleration, the faster an object's speed will change.
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Acceleration refers to increasing or decreasing speed. When an object changes its speed, it is said to be accelerating, whether the speed is increasing or decreasing. Changing direction is related to a different aspect of motion called velocity.
-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.
Acceleration is the rate at which an object's velocity changes over time. In other words, acceleration measures how quickly an object's speed or direction is changing. Velocity, on the other hand, is the speed and direction of an object's motion. So, acceleration and velocity are related in that acceleration affects the change in velocity of an object.
A change in speed (and/or direction) is acceleration.
Acceleration can be either a change in speed or a change inthe direction of the motion even if speed doesn't change.a=dv/dt
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.

Acceleration is the time rate of change of speed. Acceleration = speed/time.
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.

Speed is the rate of motion usually expressed as distance traveled per unit of time.Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.

Acceleration is the rate that speed changes.
No, angular speed refers to how fast an object is rotating around an axis at a given moment, usually measured in radians per second. Angular acceleration, on the other hand, describes how quickly the angular speed of an object is changing, or how fast the rotation is accelerating or decelerating.
