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.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How does average velocity differ from instsntaneous 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 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.


When an object moves with constant velocity does its average velocity during any time interval differ from its instantaneous velocity at any instant?

No. Its velocity, average velocity and instantanous velocity will all be the same at any (or every) time an investigator makes an observation.


Can an object's instantaneous velocity ever differ from its average velocity over a certain time interval?

If a 5 mile stretch of a bus journey lasts 15 minutes, then the average speed over this stretch was 20mph. But undoubtedly the bus achieved greater speeds than this, and it also spent time sitting still in queues. So the simple answer to the question is 'yes'. Less trivially and more interestingly: unless velocity is actually constant, then an object's average velocity over a finite time interval - and hence any empirical measurement of its speed - must (nearly always) differ from the instantaneous velocity. As the time period grow closer to zero, the measured velocity will converge on the instantaneous figure, but will never reach it.


How does a car's average speed differ from its instantaneous speed?

The average speed of a car is how fast it averages over a span of time. Instantaneous speed is how fast the car is moving at any given time which is measured using a real-time speedometer.
