    Today we are blogging to define how to find and calculate average velocity and speed, instantaneous velocity/speed and velocity. After that the class has to post five problems where someone has to calculate those problems. Know what concepts and units in questions to understand. We are going over problems to understand what concepts and units are. Know and list some differences between concept and units. Concepts do not have numbers where as units do. Class is going over formulas and what the symbols represent. When doing the problems you plug in one of two formulas ( V=d/t or V=AxT ) to where it applies. Class got definitions for the terms needed.

  2. Average speed- How far you go and how long it took. Velocity- How fast you were going at a specific time. v=axt Acceleration- any change in speed. v=axt

  3. Average velocity/speed- Rate distance changes over some time interval. How far/How long it took.

    Instantaneous velocity/speed- How fast you at a SPECIFIC time. V=AxT

    Acceleration- Any change in velocity/speed. V=AxT

  4. 1) Average velocity and speed- Rate your distance changes over sometime memorable.
    v=distance divided by time.
    2) Instantaneous velocity and speed- How fast your going at a specific time. v=a times t
    3) Acceleration- Any change in velocity.
    v=a times t

    For average speed its the rate the distance changes over the sometime intervolt meaning how far you went and how long it took.
    velocity is how fast you were going at a specific time. v=a*t
    Acceleration is any change in speed. v=a*t

  6. Average speed- The rate the distance changes over a time interval.
    Instantaneous speed- How fast you were going at specific time. V= a x t
    Acceleration- Any change in velocity or speed. V= a x t

  7. average speed: the rate your distant changes over some time interval
    velocity: how fast you are going at a specific time
    acceleration: any change in velocity

    1) average speed-how far you go and how long it took
    2) instantaneous speed- how fast you were going at a specific time
    3) v=at
    4) acceleration-any change in velocity
    v=at

  11. 1)average velocity-the rate your distance changes over
    2)instantaneous- how fast you were going at a specific time
    3)acceleration-any e in velocity

  12. average speed is the rate distance changes during some time inteervol
    or how long you go.
    A speed how fast you where going at a specific time


    v=a times T
    ac any chage in speed

  13. verage velocity and speed-
    the rate your distance changes over some time intervole

    instantaneous speed:
    how fast you were going at a specific time.
    v= a (t)

    acceleration
    any change in velocity
    v=a(t)

  14. 1)average speed the rate your distance changes over some time interval v=d/t
    2)instantaneous speed is how fast you are going at a specific time v= a*t
    3)acceleration is any change in velocity v=a*t

  15. Average velocity/speed- Rate distance changes over some time. How far/How long it took.

    Instantaneous velocity/speed- How fast you at a "specific" time. V=AxT

    Acceleration- is the change in velocity over the change in time V=AxT

  16. 1. Average speed how far you go and how far it took.
    2.instantaneous how fast you were going at a specific time.
    3.Acceleration is any change in velocity.

  17. Average speed is defined as the rate at which distance changes over a time interval. v=d/t

    Instantaneous speed is defined as the rate at which distance changes at a specified time. v= a*t

    Acceleration is defined as any change in velocity v=a*t

    1. Average speed - the rate distance changes,or in other words it means "how far you go and how long it took.the formula is V=d/t.
    2. Instantaneous speed/velocity - how fast you were going at a specific time. the formula is "V= a*t".
    3. Accelaration - any change in acceleration or speed.the formula is V=a*t.
