position or displacement
it depends on whether you are considering it a vector or a scalar
The speed of an object at any instant in time is its instantaneous speed.
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.
That is called the instantaneous speed.
Instantaneous speed is speed at any instant in time.
Velocity is change in displacement over time.
velocity is your answer.
The speed of an object at any instant in time is its instantaneous speed.
Speed of an object at one instant of time is the object's instantaneous speed.(Not velocity.)
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.
If the instant is finite, the object is in the position indicated on the graph
acceleration
Distance traveled by an object per unit of time is called speed. Speed is a scalar quantity. It is always greater than or equal to zero. Direction is not associated with this physical quantity. Speed at any instant is called instantaneous speed. Speedometer in vehicles show instantaneous speed viz. speed at any instant of time. Speed at any instant = derivative of traveled distance with respect to time = dx/dt.
The speed of an object at one instant of time is its instantaneous speed.
the rate at which an object is moving at a given moment in time.
The velocity of an object at a particular instant or at a particular point of its path is called instantaneous velocity. In another word, the instantaneous velocity of an object is defined as the limiting value of the average velocity of the object in a small time interval around that instant , when the time interval approaches zero. v = dx/dt , where dx/dt is the differential coefficient of displacement "x" w.r.t. time "t"
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.
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.
