Question

Define acceleration and write is si unit and dimensional formula.​

Answer 1

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.

Answer 2

A vehicle's capacity to gain speed is called accerlaration.

The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

SI unit: m/s2, m·s−2, m s−2

Dimension: L T −2

Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T−2. The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

SI unit: m/s2, m·s−2, m s−2

Dimension: L T −2
