The Mathematical Language of Speed and Velocity

HW:  Review reading through today's lecture. 

Equation of Speed

Mathematical Definition: 

Equations of Velocity

The Average Velocity:

Slope of a position-time graph is valid for all point on the graph defining

the average velocity over the entire interval

The Instantaneous Velocity

Slope of the position-time graph is valid for just one point on the graph defining

the instantaneous velocity valid for only one position on the graph

Summary of Lecture:  Quick Recap of Today's Lecture

Instructor will give practical examples of how to solve some general problems by

presenting problems on the board with their associated solutions

Daily Topic

Practical Applications of Speed and Velocity

Review HW:

Points of Emphasis:

Students will be required to set up their problems according to the format that will teach them.

1.  Information Section:  Any and all information from each problem will be written here in an organized, neatly written, format.

2.  Any and all diagrams relevant to the problem that you are solving

3.  Perform All Conversions first:  Students may calculate conversions using their calculators.

4.  Include units with All numbers

5.  Write all steps of algebra first and plug and chug from last step of algebra.

6.  Box in Final Answer

7.  All Final Units will by SI Unless otherwise stated.
