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.
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.
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.
When Velocity of particle equals average velocity equals instantaneous equals speed is possible?
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
When average velocity is equal to its instantaneous velocity acceleration?
you are still. motion is at rest.
What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
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.
Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
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 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.
You want correct formula for instantaneous velocity?
v(t) = dsdt This should be the formula for instantaneous 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.
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.
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.
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.
