Physics - Unit 2
Kinematics (the study of motion)
By the end of this unit, you should be able to do the following:
1. You should be able to determine the average velocity of an object in two ways: by determining the slope of an x vs. t graph and by using the equation .
2. You should be able to determine the displacement of an object in two ways: by finding the area under a v vs. t graph and by using the equation .
3. Given an x vs. t graph, describe the motion of the object (starting position, direction of motion, velocity, acceleration), draw the corresponding v vs. t graph, draw a motion map for the object, determine the average velocity of the object (from the slope) and write the mathematical representation that describes the motion.
4. Given a v vs. t graph, describe the motion of the object (direction of motion, how fast, acceleration), draw the corresponding x vs. t graph, determine the displacement of the object (from the area under curve), draw a motion map for the object and write a mathematical representation to describe the motion.
5. Use the three kinematic equations to solve problems involving motion.
This unit is our introduction to kinematics - the study of motion without reference to the forces causing the motion. We will learn the formulas that apply to Uniform Accelerated Motion but more importantly we will learn how and when to apply these formulas for real-life problem solving.

PosPhysics 4.9
Rocket lab!
For the lab you will be timing how long your rocket is in the air. We are assuming that our rocket moves directly up and comes straight back down. Using the time that your rocket was in the air, calculate a) how high the rocket went and b) launch velocity. NEATLY show your work (SHOW FORMULAS!!) and include a photo of your rocket. You can be in the photo if you want to. All of this will be turned in on a single sheet of paper (not notebook paper). There will be 3 winners: best design, best paper/photo/physics work, and HIGHEST flight.
