MOO MOTION

PARTICLE MOTION AND CURVE SKETCHING RIZZI – CALC BC

POSITION, VELOCITY, AND ACCELERATION s(t) tells us position v(t) tells us velocity (how fast/what direction) a(t) tells us acceleration (changing speed/what direction) Speed is velocity (minus direction) Objects speed up if velocity and acceleration work in the same direction (ie, both positive or both negative) Objects slow down if velocity and acceleration work in opposite directions (ie, one is negative and one is positive)

PARTICLE MOTION A particle is moving along a horizontal line with position function as given. Find the following: a)Intervals where the particle is moving right and left b)When the particle is stopped c)Intervals where the particle is speeding up and slowing down

CURVE SKETCHING Use what you know about algebra and calculus to sketch the graph of the following curve. You will have to rely on your knowledge of: Factoring x- and y-intercepts Critical points Intervals of increasing/decreasing Relative extrema Intervals of concavity Points of inflection

PARTICLE MOTION REVIEW QUESTION 1.When is the particle moving to the right? To the left? 2.Describe the acceleration of the particle. When is it speeding up? Slowing down?
