This text is meant to accompany class discussions. It is not everything there is to know about uniform circular motion. It is meant as a  prep for class. More detailed notes and examples are given in the class notes, presentations, and demonstrations (click here.)

Objectives
Students should be able to:
1 Draw and label a picture of the problem showing numbers and units
2 Draw a triangle showing the initial velocity, its angle, and its horizontal and vertical components.
3 Draw this triangle with vectors.
4 List givens with units in a table.
5 Describe what is being calculated.
6 Show the equation with only variables.
7 Isolate the unknown showing only the letter variables.

8

Show equations with the numbers AND units.

9

Show the answer with the correct sig. figs. and units
10 Calculate and the following given the initial velocity, (magnitude and direction,) and one other "given."

 a Height to apogee b Time to apogee c Time in the air d Range e Landing height f Impact velocity (magnitude and direction,) with a vector triangle of the impact velocity's components. g Given the range you can calculate the height. h Given the height, you can calculate the range. i Directions and signs of the variables.
11 You will do this involving problems that set up like any of the following for problems where the initial velocity is up or down at an angle

 a Lands at the same height as the start height. b Lands higher than the start height. c Lands lower than the start height. d Rolls horizontally off a surface to a landing below
