OBJECTIVES:
2. Use mathematical and computational thinking to apply formulas related to an object’s displacement, constant velocity, average velocity and constant acceleration. Interpret the meaning of the sign of displacement, velocity, and acceleration. 3. Obtain information to communicate the similarities and differences between distance and displacement; speed and velocity; constant velocity and instantaneous velocity; constant velocity and average velocity; and velocity and acceleration. |

BELLWORK:
-> How do you calculate average velocity? -> How does average velocity and speed differ? -> Consider a Nascar driver, if their average speed was 50m/s. How long would it take for them to travel the 5000m lap? After completing five laps, what is the car's average velocity? CLASSWORK: 1. Short presentation on Constant Velocity and Acceleration 2. Practice problems in small groups (pdf or doc). 3. Work in groups on garden project. HOMEWORK: -> One Dimensional Review Questions |

BELLWORK:
-> What controls motion of objects moving vertically? -> A student drops a rock off of a bridge, does the rock increase or decrease in speed? Why. CLASSWORK: 1. Review problems. 2. Practice Problems on Free Fall 3. Free-Fall Problems Practice 1 - A rock is dropped off a cliff that is 105 m tall. a. How long will it take to hit the ground? b. What is the rock’s final velocity? Practice 2 - A ball is thrown directly upward with an initial velocity of 22.5 m/s. a. How long will the ball take to reach its maximum height? b. What maximum height will the ball reach? c. How long will the ball be in the air? d. What is the ball’s final velocity (when it hits the ground)? 4. 1D Motion Packet HOMEWORK: -> Finish Packet |
