  1. Outline Speed and Velocity • Average speed • Velocity • Predicting the future 1524 2761 Mdcl1 Mdcl!

  2. Average Speed Distance traveled Time spent traveling Average speed = OR Not a vector! Not a vector!

  3. Example 1 – Av Speed Example 1 – Average Speed If a car travels 100 km/h for an hour, and then travels 50 km/h for an hour. The average speed is given by:

  4. Average Velocity Displacement Time spent traveling Average velocity = OR Vector! Vector!

  5. Example 2 – average velocity QQ6 Av Speed A particle moving along the x-axis is located at xi=12m at t1=1s and at xf=4m when tf=3s. Find its displacement and average velocity during this time interval.

  6. Example 3 – average velocity QQ6 Av Speed The position of a particle moving along the x-axis varies in time according to the expression x=3t2, where x is in m and t in s. Find the displacement and the average velocity for the particle between t=1s and t=4s

  7. Quick Quiz QQ7 Av Speed An athlete swims the length of a 50m pool in 18s and then makes the return trip to the starting position in 20s. Determine his average velocity in the second half of the swim: • 0 m/s • 2.5 m/s • -2.5 m/s • -5 m/s

  8. Position from Velocity  but  

  9. Example QQ7X vector equation An object starts at r1=3m. It is moving with an average velocity of vavg= 2m/s.What is its position after a time interval of Δt=5s? Get TAs to assist with the physics
