9 Graph QuestionWhat is the magnitude of the object’s total displacement after 4 secondsWhat is the average speed after 3 seconds?8mV= d/tV= 8m/3sV= 2.66 m/s
10 SummaryDistance and time measurements can be used to describe the velocity and accelerationThe Shape of the Distance vs. Time determines the type of motionRest : Straight line parallel to time axisConstant Speed : Straight line on a slope (magnitude of the speed)Constant Acceleration: Curved lineThe Shape of the Velocity vs. Time determines the type of motionRest : Straight line on the time axisConstant Speed : Straight line parallel to the Time axisConstant Acceleration: Straight line on a slope (magnitude of the Acceleration)
