2. What is average velocity? m/sec = m/sec m = m/s * sec

3. What is average velocity?

4. What is Instantaneous velocity? m/sec = m/sec m = m/s * sec

5. What is Instantaneous velocity? m/sec = m/sec m = m/s * sec is made very small – infinitesimally small What is Instantaneous velocity?

7. Finding instantaneous velocity Find the slope using small values of t and d. Find the tangent to the line of d vs t.

8. What is Instantaneous velocity? V2 V3 V1
