Answer 2

Answer:

1)A body is said to be in uniform acceleration when it is increasing its speed equally in equal intervals of time. A body is said to be in non uniform acceleration when it is increasing unequal amount of speed in equal intervals of time.

2)

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
