What is a instantaneous velocity?
Instantaneous velocity is the velocity of an object at a specific instant in time. It is the rate of change of position of an object with respect to time at that exact moment. This instant velocity may differ from the average velocity over a given time interval.
Define speed at which an object is moving at a given instant time?
If the displacement of the object (its position) can be described as a functional or algebric equation, you can find the instant speed of this object by calculating the derivative of its displacement equation, knowing that speed is the first derivative of position and acceleration, its second.
Difference between instantaneous and average velocity?
average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)
How the velocity can be determined by displacement time graph?
The velocity of an object can be determined from a displacement-time graph by calculating the slope of the graph at a specific point. The slope at a given point represents the instantaneous velocity of the object at that point. The steeper the slope, the greater the velocity, with positive slopes indicating motion in one direction and negative slopes indicating motion in the opposite direction.
When will the average acceleration be equal to instantaneous velocity?
Never.Average velocity is total displacement (final position minus initial position) divided by the total time: vave = (xf-xi)/tAcceleration is the rate at which your velocity is changing or change in velocity over time: a= (vf-vi)/tThese two quantities may have the same numerical value but will never have the same units.Average velocity for a trip can equal instantaneous velocity at a certain point during the trip, however, at any time during a trip in which the velocity is constant or at half way through the total time of a trip where the acceleration is constant.

Speed of an object at one instant of time is the objects speed is?
Speed of an object at one instant of time is the object's instantaneous speed.(Not velocity.)

What measures the rate of change in velocity?
Police measur speed with a radar gun. It uses the Doppler effect to find speed. You can measure distance traveled and use a stopwatch to measure speed yourself. You asked about velocity, however. Velocity is the combination of speed and direction. To measure velocity, you have to track the direction of travel. For that, either a compass, a chart or some other measure.

Instantaneous speed is measured how?
Instantaneous speed cannot be measured because it is a theoretical construct. It is the speed that an object has at one particular moment, but measuring the speed of an object necessarily involves several moments so you can only measure the speed over some finite amount of time.
How can one determine the vertical acceleration of an object?
To determine the vertical acceleration of an object, you can use the formula: acceleration change in velocity / time. Measure the change in velocity of the object moving vertically and divide it by the time it took for the change to occur. This will give you the vertical acceleration of the object.
Speed of an object at one instants of time objects speed?
The speed of an object at one instant of time is its instantaneous speed.
You do not know an objects velocity until you know what?
To know an object's velocity, you need to know its speed and direction. You can measure speed by calculating how long an object takes to arrive at a new position. So by knowing an object's starting position, ending position, and the time it took to get there, you can calculate its average velocity. In a more advanced calculation, you could choose starting and ending positions that are extremely close to one another and calculate "instantaneous velocity." Velocity is known as a "vector value". A vector not only has a length, but a direction. In this case, "length" is the same as "speed", and direction is its change in position.
How can one determine the position of an object based on its velocity?
One can determine the position of an object based on its velocity by integrating the velocity function over time. This will give the displacement of the object from its initial position.
