UNIT 2 CONSTANT VELOCITY MOTION BUGGY LAB CONCLUSION VELOCITY AND INSTANTANEOUS VELOCITY

OBJECTIVES • I CAN… • CALCULATE AND DESCRIBE THE IMPORTANCE OF THE SLOPE AND Y-INTERCEPT OF A POSITION VS. TIME GRAPH. • GIVE A DEFINITION FOR AVERAGE VELOCITY, AVERAGE SPEED, AND INSTANTANEOUS VELOCITY. • CALCULATE THE AVERAGE VELOCITY OF AN OBJECT FROM A GRAPH OF POSITION VS. TIME. • DRAW 2 GRAPHICAL REPRESENTATIONS OF AN OBJECT’S POSITION VS. TIME.

LAB: PHYSICS BUGGY • HOW DID THE PHYSICS BUGGY’S DISTANCE CHANGE OVER TIME? • HOW WOULD YOU DESCRIBE THE RELATIONSHIP?

LAB: PHYSICS BUGGY • HOW DID THE PHYSICS BUGGY’S DISTANCE CHANGE OVER TIME? • HOW WOULD YOU DESCRIBE THE RELATIONSHIP? • HOW DID YOU DETERMINE THIS FROM THE GRAPH?

LAB: PHYSICS BUGGY • HOW DID THE PHYSICS BUGGY’S DISTANCE CHANGE OVER TIME? • HOW WOULD YOU DESCRIBE THE RELATIONSHIP? • HOW DID YOU DETERMINE THIS FROM THE GRAPH? • WHAT EQUATION DID YOU DERIVE FROM THE DATA/GRAPH?

Position vs. Time General Equation/Fit = Position (m) Time (s)

Position vs. Time General Equation/Fit = What does the Y-Intercept mean? Position (m) Time (s)

Position vs. Time General Equation/Fit = What does the Y-Intercept mean? What does the Slope mean? Position (m) Time (s)

A FEW MORE SYMBOLS… SYMBOL PRONOUNCIATION MEANING xi xf t ti tf “X initial” Initial x-position “X final” Final x-position “T” Time (as a variable, any time measurement) “T initial” Initial time (starting time) “T final” Final time

Y = M X + B

Y = M X + B Xf

Y = M X + B Xf = t

Y = M X + B T + Xi Xf =
