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:
-> Is it possible for an object to be in motion if no net force is acting on it? Explain. -> If an object is at rest, can we conclude that no external forces are acting on it? Explain. CLASSWORK: 1. Conceptual Question Review: -> A beach ball is left in the bed of a pickup truck. Describe what happens to the ball when the truck accelerates forward. -> Explain why must a person climbing a rope pull downward on the rope in order to move upward. -> Explain why pushing pushing downward on a book to slide it across the table increases the fiction between the table and the book. 2. Frictional Force Practice Problems: -> A student moves a box of books down the hall by pulling a rope attached to the box. The student pulls with a force of 185 N at an angle of 25 degrees above the horizontal. The box has a mass of 35.0 kg, and the coefficient of friction between box and floor is 0.270. Find the acceleration of the box. HOMEWORK: -> Work on portfolio and project. -> Review Problems. |

BELLWORK:
-> If a baseball and a cannonball are dropped within a vacuum from the same height at the same time, which ball will hit the ground first? a. the cannonball b. the baseball c. The balls land at the same time. d. the ball with the larger volume -> An ice skater at rest pushes against a sled at rest, causing both the skater and sled to move away from each other with different accelerations. This is an example best described by a. Newton’s first law of motion for objects at rest. b. Newton’s first law of motion for objects in motion. c. Newton’s second law of motion. d. Newton’s third law of motion. CLASSWORK: 1. Frictional Force Practice Problems -> A 75kg box slides down a 25 degrees ramp with an acceleration of 3.60 m/s2 . Find the uk between the box and the ramp. What acceleration would a 175kg box have on this ramp? 2. Complete Newton's Law of Motion Review 3.
