Hey mate,Here is your solution.
Explanation:
Non-Uniform Speed : When a body covers unequal distances in equal intervals of time, then that body is said to be in non uniform speed.
For e.g., an object thrown into air, like stone, moves at non-uniform speed, lift used to go up or down in a building.
Non-Uniform Velocity : When the velocity is not uniform i.e. not constant. This implies that the velocity of the object moving with non uniform velocity is either increasing or decreasing with time i.e. the object is accelerating or decelerating.
Since velocity is a vector quantity, hence it depends on two factors namely speed and direction.
If any of the two will change, velocity will also get changed.
So, we can say that the object is moving with non uniform velocity, if an object is :
1. changing speed wrt time but in the same direction.
2. changing direction wrt time while moving with constant speed.( e.g., motion of a particle in a circular path with constant speed)
3. changing both speed and direction wrt time.
UNIFORM, VARIABLE AND AVERAGE SPEED - DEFINITION
Uniform Speed: A body is said to be moving with uniform speed, if it covers equal distances in equal intervals of time.
Variable Speed: A body is said to be moving with variable speed if it covers unequal distances in equal intervals of time.
Average Speed: Average speed of a body is defined as that uniform speed with which it covers the same distance in a given interval of time as is actually covered by it in the same interval of time while moving with variable speed.
It is given by the ratio of the total distance travelled by the body to the total time taken by it.
