Change in velocity divided by time is acceleration, but velocity divided by time has no particular significance.
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
Because it is calculated as the limiting value of the change divided by the time taken for the change, the limit being taken as the time interval becomes infinitesimally small. That is how the derivative with respect to time is defined.
V = d / tVelocity is the change in distance over an interval of time.
Velocity = distance divided by time / Velocity = average speed over time / Acceleration = (change of) velocity divided by time elapsed Change in velocity = final velocity "minus" initial velocity divided by time elapsed
Average velocity is change in position (displacement) divided by the interval.
A change in position and an interval of time.
Acceleration = (change in speed) divided by (time interval)

It is acceleration. The difference between final velocity and initial velocity, divided by the time is the AVERAGE acceleration. Remember, though that velocity is a vector. So if you are going round in a circle at a constant speed, your direction of motion is changing continuously and so you are always accelerating!
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
(change in distance) divided by (time interval) = the object's average speed during that time interval.
Instantaneous speed:- It is the rate of change of position with respect to time,at that instant. Average speed:-Average speed is defined as the total path length travelled divided by the total time interval.
Definitely.A car that does zero to 60 in 6 seconds will jam you back into the seat a lot harderthan a car that does zero to 60 in a half hour.Average acceleration is (change in speed) divided by (time to make the change).You can see that the change in speed and the time interval of the change are equally important.
Technically because it would require infinite power. Stopping requires a change in energy. Power is defined in the change in energy divided by the time over which the change occurred. In an instant stop, the time interval is zero. With a zero in the denominator, your power approaches infinity. Practically, there is no way to implement tires that could stop a car instantly, as well as many other issues.
A material's density is defined as its mass per unit volume. It is, essentially, a measuremement of how tightly matter is crammed together. The principle of density was discovered by the Greek scientist Archimedes.In kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity. The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval; the instantaneous speed is thelimit of the average speed as the duration of the time interval approaches zero .
