Unit: Measurement

Page history last edited by Shu-Yee Chen 10 years, 6 months ago

Unit: Measurement (Speed, Distance, Time)

 

Science and Engineering Practice-Engineering Design: Prototype this goes through the Engineering Design Process, which is something we will be exploring throughout the year in Introductory Physics. We will be kick-starting the year with a building exercise that outlines the whole process.

 

Central Concept-The Metric System and SI Unit: The Metric System is used Internationally in the Scientific Community. It is based on standard prefixes in power of 10. The Simpson's Intro shows how power of 10 works, a spoof of the original video: http://designnotes.info/?p=3305

 Here is the original Powers of 10 Video: (A classic!!!): http://youtu.be/0fKBhvDjuy0

 

Central Concept-Average Speed: Speed is an important concept in everyday life. In particular, average speed is often used in extrapolate important information such as driving directions and estimated time. We will begin to explore how speed of an object is determined and how we can use the physics definition of average speed to understand the rate of change of a position.

 

Learning Objectives:

By the end of this unit, you should be able to.... (Those in bold will be essential & will be assessed formally in the curriculum)

1.
Understand and utilize the engineering design process   
2.
Measure with reasonable accuracy and precision. 
3.
Identify the limitations and advantages of different measuring tools.
4.
Distinguish between Instrumental and Operational errors.
5.

Accurately record data at the time of observation with the correct units.

6.

Identify appropriate standard international units of measurement for length (meters) and time (seconds), speed (meters/second) and the prefixes milli-, centi-, and kilo-.

7.

Describe motion using the average speed equation.

8. Measure or Calculate the average speed, distance, time of an object using the average speed equation.
9. Use dimensional analysis (Unit Conversion) method to calculate the average speed of the students in the classes during their measurement activity. (Challenge Option)
