Unit Conversion, Significant Digits and Scientific Notation Review 1.Make the following unit conversions: (a) 0.00245 km to m (b) 7 365 226 µN to N (c) 356 223 565 g to Mg 2.Determine the number of significant digits: (a)0.694 (b)0.003824 (c)1504 (d)36000 (e)36000.0 3.State the number in scientific notation and proper significant digits: (a)0.000235 to 2 s.d. (b)145 387 to 3 s.d. (c)543.685 x 10 5 to 4 s.d. With a partner: 4.Create one multiplication/division question 5.Create one addition/subtraction question **** you must know the answer to your question!

2. Unit 1 - Kinematics In this unit you will be able to: 1.Define and describe motion concepts such as distance, displacement, speed, velocity, and acceleration 2.Interpret patterns observed on various types of motion graphs 3.Apply equations relating the variables associated with kinematics 4.Use vector diagrams to analyze motion in two dimensions 5.Solve various types of projectile motion problems

3. Kinematics Kinematics – the study of motion Motion – when an object is continuously changing its position with respect to its surroundings There are two basic types of motion: 1.Uniform motion – motion in a straight line at a constant speed (not common) 2.Non-uniform – change in speed, direction or both (very common) 1.1 Prac. #1
