Question

Define acceleration and the state its formula and SI unit

Answer 1

Answer:

rate of change in velocity is called acceleration

acceleration is also defined as force per unit mass

its SI unit is metre per second.

Answer 2

Answer:

Acceleration

It is defined as the rate of change in velocity.

Mathematically;

a = v/t

SI unit of acceleration

Unit of velocity/Unit of time = m/s^2 = ms^-2

In physics or physical science

It is  vector quantity

dimension ;

→ length/time².

In SI units, acceleration is measured in meters/second² using an accelerometer.

• When velocity or direction are changed, there is acceleration (or deceleration)
