Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken.

As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.

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

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


Difference between instantaneous and average velocity?

Average velocity is simply displacement over time. Instantaneous velocity is the velocity at any given instant, or the displacement over an infinitely small amount of time.


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.


What is the Instantaneous velocity?

Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.


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.


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.


Difference between average velocity and instantaneous velocity?

average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)


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.


Is instantaneous velocity a vector or a scalar?

Velocity is always a scalar, instantaneous or average doesn't matter.


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 will the average velocity be equal to instantaneous velocity?

In uniform motion.
