2-Irregular speed

The relation (distance - time)
graph for an object moves at
non-uniform speed is
represented as a curved line
passing by the origin point.

Acceleration:

Acceleration: -It’s the change of an object’s speed in one second

Measuring unit of acceleration: (m/s2 or Km / hr2)

Acceleration = ??????????? ???? ?????????? = ??????????/???????????? = meter/second²

???????? ????????????

Uniform acceleration: It’s the change (increase or decrease) of the
object’s speed by equal values through equal periods of time.
