Question

Under what conditions is the following relationship applicable? average velocity= Initial velocity + Final velocity/ 2​

Answer 1

Answer:

When an object is not under uniform velocity and is undergoing acceleration at certain point of time. Then the arithmetic mean of its initial and final velocity is considered as it's average velocity of its motion.

Answer 2

Under what condition(s) is the following relationship applicable?

${\small{\underline{\boxed{\pmb{\sf{\bullet \: Average \: velocity \: = \dfrac{Initial \: velocity + \: Final \: velocity}{2}}}}}}}$

Condition(s) are mentioned:

We can use the given relationship if there are only two velocities are given and we are asked to find out the average velocity. Here, there is no time will be provided, there no displacement will be provided. For example,

→ If BrainlyButterfliee is going for shopping and she first travel with a velocity of 20 metre per second afterwards at the ending of the trip her velocity will be 30 metre per second, then what about the average velocity of BrainlyButterfliee!?

• Here we can apply the above relationship as we don't know about the displacement and time here. We just know about the initial and final velocity of BrainlyButterfliee.

In such type of condition(s) we can use the given relationship.
