Question

What is acceleration? State its unit and types.

Answer 1

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.

Answer 2

Answer:

The rate of change in velocity is called acceleration. It's SI unit is m/ sec^2 .

Acceleration can be of two types: positive and negative. Negative acceleration is termed as Retardation.
