Question

what is an acceleration? what's the difference between velocity and acceleration? is there any device available to measure acceleration?​

Answer 1

Answer:

acceleration :In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (they have magnitude and direction).[1][2] The orientation of an object's acceleration is given by the orientation of the net force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law.[3],

difference

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared

Answer 2

Answer:

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 direction—or change both.

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.

An accelerometer is a device that measures acceleration, which is the change in an object's velocity per second. ... Technically, an accelerometer measures proper acceleration, which is not the same as coordinate acceleration. This means that the accelerometer can be used to detect the direction of gravity.
