Question

define acceleration and give its mathematical expression ​

Answer 1

Answer:

$\huge\sf\underline{\underline{\pink{✤ Answer:-}}}$

In physics or physical science, acceleration (symbol: a) is defined as the rate of change (or derivative with respect to time) of velocity. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second² using an accelerometer.

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 second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Answer 2

Answer:

Acceleration: Acceleration is the rate of change of velocity. Once there is a change in velocity, the object is said to be accelerated.

Here is the formula:

a = {v-u}{t}tv−u

In the formula,

u - Initial velocity

v - Final velocity

t - Time.

Acceleration is a vector quantity.
