Linear Motion - A study of the motion of objects.

Test date (September 9-10, 2002) workQuiz (September 8, 2002)

This unit will allow each student to:

- gain a better understanding of the concepts of speed, velocity and acceleration as well as describing them visually through the use of graphs
- continue making proper scientific measurements and calculations w/ significant digits
- define and properly use all vocabulary
- properly apply all terms in describing/explaining real world examples
- relate these concepts her/his daily activities and behaviors
- teach someone else the concepts discussed
- practice proper laboratory safety

- identify and apply the main steps of the scientific approach to problem solving
- perform and identify proper scientific measurements which are both precise and accurate
- identify the precision of a measuring instrument based on seeing the instrument and/or the resulting measurement
- identify the number of significant digits in a measurement and their purpose
- report results of measurement calculations according to basic significant digit rules
- identify SI prefixes and their numerical values (pico - giga)
- identify common SI base units as well as the related USCS units
- convert from SI to SI units
- convert from SI to USCS units and vise versa using dimensional analysis (unit cancellation)
- write measurements in scientific notation format
- perform calculations involving scientific notation
- describe a moving object with relation to a frame of reference
- distinguish between distance and displacement
- distinguish between speed and velocity
- identify vector and scalar quantities
- distinguish between change in velocity, average velocity, and constant velocity
- describe the motion of an object undergoing acceleration
- recognize and relate SI and USCS units of time, distance, speed, and acceleration
- recognize a speed, velocity, and acceleration by the units only
- interpret (a) distance vs. time (b) position vs. time (c) speed vs. time and (d) velocity v. time graphs
- construct (a) distance vs. time (b) position vs. time (c) speed vs. time and (d) velocity v. time graphs from given data
- collect necessary data from a given scenario to construct a position v. time graph
- perform calculations using proper problem solving techniques to determine (a) speed, time, or distance (b) velocity, displacement, or time and (c) acceleration, change in velocity, or time
