    Speed unit 1 test review Speed unit 1 test review Presentation Transcript

    • SPEED!
    • CALCULATING SPEEDSpeed = Distance traveled Or s = d Time elapsed t • Example: If a runner travels 100 m in 10 seconds what was his average speed? • So, what are the units for speed? • How would you re-arrange this formula to solve for… • Distance? • Time?
    • CONSTANT SPEED• A moving object that doesn’t change it’s speed travels at constant speed• Constant speed means equal distances are covered in an equal amount of time
    • WHAT TIME KNOW FOR TEST ON FRIDAY• Measurements: how to read a measurement scale, SI/english units • SI Units: Must know conversion factors from kilo- to milli- • Know how to convert numbers between unit prefixes• Precision & accuracy: how to determine if data is precise or accurate• Significant figures: Determining the number of significant figures in a given number, determining sig figs in math operations• Scientific notation: converting from standard form to scientific notation, scientific notation to standard form, and math operations for scientific notation• Factor label method: converting units• Speed: using the speed equation, graphing speed, converting between speed units• Algebra of physics: rearranging equations to solve for a variable.
    • WHAT TIME KNOW FOR TEST ON FRIDAY• What to do: • Review and re-do homework problems • Review labs we have done in class • Re-read class and textbook notes • See powerpoints from class on website • Review vocab for this unit
    • EXAMPLE: MEASUREMENTS
    • EXAMPLE: SIGNIFICANT FIGURES• 0.00404• 30080• 30080 + 10.004• 30080 x 20.0
    • EXAMPLE: CONVERSIONS• Convert 3.00x10 8 m/s (the speed of light) to mph
    • ALGEBRA OF PHYSICS• In physics, we will be re-arranging a number of equations in order to isolate a variable on one side of the equation to solve for an unknown. Let’s freshen up on these skills!• Rearrange the following equations to solve for x: a = 3x + b ½ x2 +3 = y 5(x + y) = z ½h=j+½x
