## Related Questions For the instantaneous value of average velocity, average speed and average velocity are equal. average velocity means change in displacement and time interval ratio is called as average velocity average velocity what is the velocity at particular instant of time Velocity is speed and its direction. Average velocity is average speed and its direction.  Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement. Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement. Average velocity is the distance traveled divided by the time it takes to travel that distance. Average velocity is also called "velocity".  The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do. velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same. No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time). Average velocity = displacement over time The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity. To calculate Average velocity: ( Vf - Vi ) / t Where Vf is Final Velocity Vi is Initial Velocity t is Time At a small time interval, the average velocity is approximately equal to the instantaneous velocity. However, the values of the average velocity and the instantaneous velocity approach each other , as the length of the time interval is decreased more and more. The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity. Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger. The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity. Average velocity is zero if the displacement is zero. Average velocity = Displacement/Time = 0/Time = 0.  It is not. Average acceleration is (change of velocity)/(time for the change)   The tangent at a point on the position-time graph represents the instantaneous velocity. 1. The tangent is the instantaneous slope. 2. Rather than "average" velocity, the slope gives you "instantaneous" velocity. The average of the instantaneous gives you average velocity. ###### Math and ArithmeticDefinitionsPhysicsScienceHydraulics Copyright © 2020 Multiply Media, LLC. All Rights Reserved.
