Question

How do you find the velocity of non-uniform or uniform objects?

Answer 1

Answer:

by using velocity formulas

Explanation:

uniform velocity :- d=v/t

and same for non uniform also

Answer 2

Explanation:

Uniform Motion:

In a uniform motion, the body covers equal distances in equal intervals of time. That means it has a constant velocity over the given period of time. By looking at the x – t, and v – t graph we can say what kind of motion it is. First, we will take x – t graph:

the slope is constant. Therefore,

Change in displacement/Change in time = Constant

So the motion is uniform. Similarly, if we take a v – t graph and the plot is horizontal or parallel to the time axis then the motion is uniform as it covers equal distance in equal interval of time.

Non-uniform motion:

As the name suggests that a motion in which the body covers unequal distances in equal intervals of time is known as a non-uniform motion. Let’s see the following v – t graph:

We know are under v – t graph represents displacement of the body. As we can see for the same time interval the area under A and B are different. So this is a non-uniform motion. So with respect to non-uniform motion we usually define average velocity. The average velocity formula is:

Average Velocity = Change in displacement/Time Taken

From the equation of motion,

Displacement = ut + 12at2

Average Velocity = ut + 12at2t

= u + at2

From first equation of motion,

Average velocity = u + v − u2

Average Velocity = v + u2

Where, v = Final Velocity

u = Initial Velocity

Similarly, we can define average speed. The formula for average speed is given us:

Average speed = Change in distance/Time Taken
