What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
What is the scientific symbol for instantaneous velocity?
The symbol for instantaneous velocity is vi.
What is the Instantaneous velocity?
Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
Is instantaneous velocity a vector or a scalar?
Velocity is always a scalar, instantaneous or average doesn't matter.
Does the slope of a position time graph represent average velocity or rate of change of velocity?
The tangent at a point on the position-time graph represents the instantaneous velocity. 1. The tangent is the instantaneous slope. 2. Rather than "average" velocity, the slope gives you "instantaneous" velocity. The average of the instantaneous gives you average velocity.
When is the average velocity is equal to the instantaneous velocity?
At a small time interval, the average velocity is approximately equal to the instantaneous velocity. However, the values of the average velocity and the instantaneous velocity approach each other , as the length of the time interval is decreased more and more.
Are instantaneous velocity and velocity the same thing?
No.Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.
How is instantaneous velocity different from average velocity?
Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.
When is the instantaneous velocity equal to avg velocity?
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
What does instantaneous velocity mean?
Instantaneous velocity is a vector quantity representing the velocity Vi at any point.It is the time rate of change in displacement.
Is instantaneous velocity a vector quantity?
"Velocity" is a vector quantity. This also applies to instantaneous velocity. If you want the scalar quantity, you talk about "speed".
What is the relationship between average velocity and instantaneous velocity?
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
Whats the difference between average velocity and instantaneous velocity?
the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object
What is the difference between instantaneous velocity and instantaneous speed?
Speed, instantaneous or not, is a term used for how fast an object travels. Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.
When an object moves with constant velocity does its average velocity during a time interval differ from its instantaneous velocity at any instant?
No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.
You want correct formula for instantaneous velocity?
v(t) = dsdt This should be the formula for instantaneous velocity.
If the instantaneous velocity of an object is constant then so is acceleration.?
It does not make sense to say that the instantaneous velocity is constant. Instantaneous velocity by definition means that it is the velocity at a moment of time. If this is a question on some homework, just say no. The acceleration, or rate of change of the velocity, is not necessarily constant.
Can the average velocity of the body be the same as instantaneous velocity?
Yes, the average velocity of the body can be same as the instantaneous velocity at a small time interval.The values of the average and the instantaneous velocities approach each other , as the length of time interval is decreased.
If the instantaneous speed of an object remains constant can its instantaneous velocity change?
Yes. Velocity is speed and direction so it can change velocity by changing direction.
When an object moves with inconstant velocity does its average velocity differ from its instantaneous velocity?
Generally it is a Yes. Instantaneous velocity is the exact velocity at a particular time in the course of the movement. However, average velocity is the average of all the instantaneous velocity over a period of time. It is also known as speed in everyday life. As a result, the movement of an object over a time period under varying velocity denotes a varying instantaneous velocity which could be different from the average velocity. It is however, possible that the instantaneous velocity equates to the average velocity at a certain point over the duration of movement. For example, a ball is traveling at instantaneous velocity of 99m/s at t=1s , 100m/s at t=2s and 101m/s at t=3s. the average velocity over the 3s period is hence 100m/s which coincides with the instantaneous speed at t=2s.
What is instantaneus velocity?
Instantaneous velocity is the velocity of an object at a specific moment in time.
When will the average velocity be equal to instantaneous velocity?
In uniform motion.
What is instantaneous speed or velocity?
It is the speed or velocity at a particular instant.
