Question

Define acceleration. Give its unit.

Answer 1

A vehicle's capacity to gain speed within a short time.

In physics, acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law. The SI unit for acceleration is metre per second squared (m⋅s−2).

SI unit: m/s2, m·s−2, m s−2

Dimension: L T −2

Answer 2

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.
