average speed
speed if no direction is needed velocity if direction is needed
The rate at which an object is moving at a given instant in time is called instantaneous velocity. This is the object's velocity at a specific moment in time, taking into account both speed and direction of motion.
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.
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.
If an object's acceleration is zero at a specific instant in time, its velocity can either be zero or a constant non-zero value at that instant. This means that the object could be either at rest or moving with a constant velocity at that particular moment.
Assuming that there is no velocity in the horizontal direction, then the velocity at that instant is zero.
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.
Instantaneous speed is the speed of an object at a specific moment in time. It is the rate at which an object is moving at a particular instant. It can be calculated by determining the distance an object has traveled in a very small amount of time.
The speed of an object at any instant in time is its instantaneous speed.
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.
Speed of an object at one instant of time is the object's instantaneous speed.(Not velocity.)
