Average velocity is calculated by the formula V = D/t, where V equals the average velocity, D equals total displacement and t equals total time.
AVERAGE VELOCITY FORMULA. v1+v2/2 i.e addition of all velocities divided by number of velocities. In the denominator, do we divide it by total time or the number of velocities given(just like we calculate normal average).
The formula for time in physics is displacement divided by average velocity, or t=Δs/Δv. What is time in physics? Time in physics is the measurement of the duration of an event.
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. The average velocity can be positive or negative depending upon the sign of the displacement. The SI unit of average velocity is meters per second (m/s or ms-1).
The correct equation for the average velocity is the second equation of the both equations you gave. The first one is correct only under given condition that the acceleration of the body is constant. Second equation even holds for variable acceleration.
The magnitude of average velocity is always either less than or equal to the average speed because displacement is always less than or equal to the distance covered. Average velocity is calculated by the formula V = D/t, where V equals the average velocity, D equals total displacement and t equals total time.
v2 = u2 + 2as is the third equation of motion. We already know that v = u + at = t = (v-u)/a or v-u = at. We already remember that distance equals average velocity multiplied by time. Therefore, s = [(v+u)/2] X [(v-u)/a] s = (v2 – u2)/2a.
To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. For example, if you traveled 50 miles in 1 hour going west, then your velocity would be 50 miles/1 hour westwards, or 50 mph westwards.
Average velocity of a body having initial velocity u and final velocity v is (u + v)/2. A body is moving with an initial velocity of u and having constant acceleration a. The final velocity v can be obtained by using which of the following equation of motion if a body covers a distance s.
It is calculated by dividing the total distance something travels by the total amount of time it spends traveling. For example, one can consider the car from earlier. If the car travels 70 miles in 2 hours, it would have an average speed of 70 / 2 = 35 miles per hour.
