Speed of an object at one instant of time is the object's instantaneous speed.
(Not velocity.)
The speed of an object at one instant of time is its instantaneous speed.
The speed of an object at any instant in time is its instantaneous speed.
An objects speed at any particular moment in time is known as its instantaneous velocity. This is the rate of change or the derivative of the objects position.
Instantaneous speed-the speed of an object at any instant time. When you ride in a car, the instantaneous speed is given by the speedometer.
The speed of an object at any given instant is its instantaneous speed, which is the rate at which the object is moving at that precise moment. To calculate the instantaneous speed, you would need to determine the object's displacement over an extremely small time interval.
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.
acceleration
Stataneous speed refers to the speed of an object at a particular instant in time. The speed could be fast or slow depending on the object and context in which it is moving.
No. Average speed is the rate an object is moving measured over more than an instant, such as one second, one minute, or something like that. Instantaneous speed, however, is the limit of the average speed as the interval of time approaches zero, i.e. at a given instant.
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
average speed
when you know both speed and direction of an objects motion you know the velocity of an object.
