What does this represent?

The change of position by an object or a particle
during the interval some people say the amount
of displacement

What is
9

• Is the total distance traveled by the particle
  during the time interval t0 to t13

10

• If given the velocity graph, then how do you know
  when the particle or object changes direction?

11

• The particle, object, or living creature will
  change directions if the graph of the velocity
  changes from positive to negative values or
  negative to positive values.
• You must be explicit specific in your
  explanation!

12

• How do you know if the speed of a particle or
  object or living creature is decreasing?

13
SPEED DECREASING

• The speed will be decreasing at some time t if
• a(t)lt0 while v(t)gt0
• OR
• a(t)gt0 while v(t)lt0.
• Please remember that you must explicitly describe
  what is happening at some specific time t.

14

• How do you know if speed is increasing at some
  specific time t?

15
SPEED INCREASING

• Speed is increasing at some specific t if
• a(t)gt0 while v(t)gt0
• OR
• a(t)lt0 while v(t)lt0
• Once again, you must be explicit about what is
  happening at some specific time t.

16

• If given position, say, s(1) and the velocity
  function, v(t), then how could you find s(8)?

17
How to find s(8)

• Remember Initial position PLUS accumulated rate
  of change
