Want this question answered?
average speed
the rate at which an object is moving at a given moment in time.
Assuming that there is no velocity in the horizontal direction, then the velocity at that instant is zero.
velocity is your answer.
speed if no direction is needed velocity if direction is needed
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.
It will travel in the direction of the velocity. I guess learning physics pays off....
Hang time does exist. When an object is tossed into the air there is an instant where it has to stop moving in order to come back down. Please note the instant is very short, but it's certainly there.
The speed of an object at any given instant is relative.
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 velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
