Differbetween
Velocity is really the differentiation of distance with respect to time. An average velocity really takes the distance covered in a given time and the average velocity will be the distance divided by time. ... A true velocity is an instantaneous quantity.

What is the difference between velocity and average velocity Class 11?
Velocity is equal to rate of change of position vector with respect to time. Average velocity is the ratio of the displacement vector to the corresponding time interval.
What is average velocity in simple words?
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.
What is U and V in velocity?
u is initial velocity. v is the final velocity. a is acceleration. t is the time period.
How is velocity calculated?
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Can velocity be negative?
Velocity is a vector quantity. If we're moving along a line, positive velocity means we're moving in one direction, and negative velocity means we're moving in the other direction. Speed is the magnitude of the velocity vector, and hence is always positive.
What is difference between speed and velocity?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
What is the formula for average velocity?
Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity.
What is initial velocity?
Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as.
Is V initial or final velocity?
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
Can initial velocity be zero?
If you choose to start looking when something is already moving, that object will have an initial velocity that is not zero. ... Well if an object starts from rest then it's initial velocity would be zero however if it is already in motion then it does have an initial velocity of greater than zero.
What is the final velocity?
Initial and Final Velocity
Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.
