Want this question answered?
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"
Velocity is the derivate of position with respect to time (i.e., the rate of change of position). Velocity is a vector (the direction is relevant). If only the number is specified, not the direction, the word "speed" is used instead. Acceleration is the derivative of velocity with respect to time; or the second derivate of position with respect to time (i.e., the rate of change of velocity).
Change in velocity divided by the amount of time needed for the change to occur;takes place when an object speeds up,slows down,or changes direction
No. As used in physics, the word "acceleration" means that THE VELOCITY CHANGES. More precisely, it refers to how quickly the velocity changes, in symbols, dv/dt.
The word speed is distance per unit of time. It is frequently used as a substitute for velocity, and it is in more common usage. But there is a difference between speed and velocity. Velocity has a direction vector associated with it. It's speed + direction. That's usually not a big deal when talking about "regular" stuff, but don't tell a physics teacher that.
Instant
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"
Independent means that it is a variable that is unaffected by other variables. For example, in terms of acceleration, velocity is the dependent variable, and time is the independent variable. Velocity is dependent upon time, but time is not dependent upon velocity. Of course, technically speaking, this is only for nonrelativistic scenarios. If velocity is extreme (near the speed of light) time IS affected by velocity in spacetime. But, that's a different issue.
That is the correct spelling of the word "instant" (an unspecified but very short time).
velocity?
Yes, the word 'instant' is both a noun and an adjective.The noun 'instant' is a word for a very short space of time; a word for a precise moment of time; a word for a thing.The adjective 'instant' describes a noun as happening or done at once; as partially prepared by the manufacturer to make final preparation easy.
The word 'instant' is both a noun, a word for a very short period of time; and an adjective that describes a noun as happening immediately. Examples:noun: I knew that was it the instant that I saw it.adjective: I have some instant soup for my lunch.
Force
A moment, a second, an instant.
Speed or velocity.
AnswerThere is instant coffee. I'm sure there's more but I can't think of any at the time.
Stenosis is narrowing, restenosis is narrowing after the lumen was widened or cleared, and you're familiar, no doubt, with the word instant. So instant restenosis means the lumen quickly narrowed again after clearing.
