Describing motion (1)

• Positions sinitial, sfinal, (or x)
• Displacements Ds sfinal - sinitial
• Instants of time tinitial, tfinal
• Time intervals Dt tfinal - tinitial
• Average Velocity vave Ds/Dt

11
Notice

• Displacement Ds can be positive or negative
• Hence so can velocity

12
Discussion

• Average velocity is that quantity which when
  multiplied by a time interval yields the net
  displacment eg.
• drive Ithaca-gtSyracuse
• average velocity(speed) useful and familiar

13
Discussion(2)

• But there is another type of velocity which is
  useful instantaneous velocity
• Eg. When I set off my velocity goes from
• 0 to 55 it varies with time and is not equal to
  my average velocity
• But it is defined in a similar way.

14
Describing motion (2)

• Average velocity (for a time interval)
• vaverage
• Instantaneous velocity (at an instant in time)
• vinstant lim

15
