The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second.

Answer 2

{AVERAGE VELOCITY}

$\huge\fbox\purple{DEFINITION :-}$

Average Velocity is the average value of the known velocities. Average Velocity is defined as the total displacement travelled by the body in time t. The average velocity is denoted by Vav and can be determined using the following formula:

$\huge\fbox\pink{AverageVelocity=TotalDisplacement /TotalTime}$

Average Velocity Problem

Problem 1: A car is moving with an initial velocity of 30 m/s and it touches its destiny at 80 m/s. Calculate its average velocity.

Answer:

Given: Initial Velocity U = 30 m/s

Final velocity V = 80 m/s

$v \: av \: = \frac{u + v}{2}$

Average velocity Vav = (30 + 80)/2

Average velocity Vav = 55 m/s
