Kinematics

This unit bundles student expectations that address how objects move in one dimension with student expectations that address skills required to effectively create and interpret motion graphs using current technology. Students become more adept at collecting data and discovering the correlation between real-life motion and the use of formulas and graphs. Students then study equations of motion in order to calculate distance, displacement, speed, average velocity, instantaneous velocity, and acceleration. They also identify and describe motion relative to different frames of reference.

Maze GameLearn about position, velocity, and acceleration in the "Arena of Pain". Use the green arrow to move the ball. Add more walls to the arena to make the game more difficult. Try to make a goal as fast as you can.

ASSIGNMENT:

1. See me for a copy of the Maze Game activity.

2. Use the link above to play the Maze Game to start familiarizing yourself with the concepts for this unit. Complete the Maze Game worksheet as you play.

ASSIGNMENT:

1. Watch the video on the displacement and distance.

2. Create a double-bubble map, comparing and contrasting distance and displacement.

3. The terms SCALAR and VECTOR should be correctly placed in your map.

Distance and Displacement Lab.docx

ASSIGNMENT: To experience the difference between distance and displacement, you may either:

1) Complete the Distance and Displacement lab included above. OR

2) ) Complete the "Princess Bride Sword Fight" Activity Above.

ASSIGNMENT:

1. Watch the video introducing velocity and speed.

2. Create a double-bubble map, comparing and contrasting speed and velocity. MAKE SURE YOU HAVE FORMULAS FOR EACH, AND I WOULD HIGHLY ENCOURAGE WRITING DOWN A PRACTICE PROBLEM!

3. Your bubble map should include the terms SCALAR and VECTOR, where appropriate.

ASSIGNMENT:

1. Watch the video on relative velocity. How does it compare to actual velocity?

2. Write 3-5 sentences describing how relative velocity is determined.

ASSIGNMENT:

1. Watch the animation over acceleration from the Physics Classroom.

2. Then, watch the youtube video introducing acceleration.

3. Write a 3-5 sentence summary about acceleration. Be sure to include the formula!

ASSIGNMENT:

1. Use the video above and create a bubble map to consolidate (put in one place) all of your kinematics equations. There is a new one in the video linking distance to acceleration and time.

2. Then, see more for a copy of the acceleration, speed and velocity problems practice and complete, choosing the appropriate formulas.

Speed, Velocity, and Acceleration Problems

Assignment: Watch the video on understanding position vs. time graphs. You may either:

1) complete the practice below over position vs. time graphs OR
2) Create your own position vs. time graph and demonstrate to me how your movements match the graph you've created.

ASSIGNMENT:

1. Watch the video on position, velocity, and acceleration vs. time graphs.

2. Then, generate 3 graphs, one of each type (velocity, acceleration, position) and write a narrative that describes what is happening in the graph to the object in motion.

ASSIGNMENT:

1.Design and implement an investigation, and formulate a testable hypothesis, to test the effect of a variable on constant acceleration using real-time technology.

2. Communicate the results of the investigation through a 5–7 minute multimedia presentation. Include the following in the presentation:

Description of the investigation (including scientific methods and safety precautions utilized)
Raw data table of displacement, time, and / or velocity
Explanation for measuring displacement, time, and / or velocity to determine acceleration
Analysis (including calculations for acceleration)
Graph showing the relationship between the tested variable and acceleration
Conclusions

This is the end of the unit!
