1 Position(x, y or z) Displacement (?x, ?y or ?z) Change in position. Depends only on initial and final positions, not on path. Includes direction. ?x = ?vdt Velocity (v) Displacement per unit time Average velocity vave = ?x/?t Instantaneous velocity v = dx/dt ?v = ?adt Acceleration (a) A change in velocity: speeding up, slowing down, or turning. Average acceleration aave = ?v/?t Instantaneous acceleration a = dv/dt Problem: Acceleration (B-1993) 1. In which of the following situations would an object be accelerated? I. It moves in a straight line at constant speed. II. It moves with uniform circular motion. III. It travels as a projectile in a gravitational field with negligible air resistance. (A) I only (B) III only (C) I and II only

Chapter 7 ? Rotational Motion and the Law of Gravity This chapter deals with rotational kinematics ? the relationships between rotational position, velocity, acceleration and time. Rotational dynamics will be discussed in the next chapter. Dynamics deals with energy, momentum, and forces. Universal gravitation is also discussed in this chapter in part since satellite and planetary motion involves rotation. Angular displacement, velocity, and acceleration Angle (() can be defined in terms of radius (r) and arc length (s) on a circle as

Chapter 7 Problems 1, 2, 3 = straightforward, intermediate, challenging = full solution available in Student Solutions Manual/Study Guide = co ached solution with hints available at www.cp7e.com = biomedical application Section 7.1 Angular Speed and Angular Acceleration 1. The tires on a new compact car have a diameter of 2.0 ft and are warranted for 60 000 miles. (a) Determine the angle (in radians) through which one of these tires will rotate during the warranty period. (b) How many revolutions of the tire are equivalent to your answer in (a)? 2. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30?, 30 rad, and 30 rev, respectively?

Arnav Sridher Period 2 Physics Collision Investigation Purpose: The purpose of this lab is to investigate the change in total momentum and total kinetic energy of an isolated 2 car collision. Procedure: Go to the website given Set up trial 1 Set a velocity for both cars as well as the mass. Make sure to follow the sheet that says what each trial should include. Press go and record the final velocity for each vehicle Repeat the steps for each trial Once you have 10 trials accounted for, calculate kinetic energy using the equation Ek=1/2(mv2) Once you have done this for the 10 trials, calculate the momentum that each vehicle has using the equation P=mv Data Table: Trials 1-4(elastic), trials 5-8(perfectly inelastic), and trials 9&10(inelastic) M1 (Kg) M2 (Kg) V1 (m/s) V2 (m/s)

Test Questions Two tugboats are moving a barge. Tugboat A exerts a force of 3000 newtons on the barge. Tugboat B exerts a force of 5000 newtons in the same direction. What is the combined force on the barge? 8000 newtons 4000 newtons 2000 newtons None of the above If two men were arm wrestling and the first man was using 15 newtons, while the other was using 10 newtons, who would win? A. Neither B. First Man C. The one using 10 newtons D. The information given is not enough to answer the question What is net force? The amount of matter in an object. How much work is being done? The total force acted upon an object. How heavy the object is. Which direction will a rope go towards to when an unbalanced force is acted upon it? Nowhere Towards the unbalanced force Right Left

Paragraph 1- Materials and Procedure Materials: 1 Pop Bottle 1 Balloon 1 Straw Duct Tape Scissors 1 Rubber Band Step 1: We wrapped our pop bottle in zebra duct tape for easy floating in the water. Step 2: Made an opening in the cap for the straw to go through. Step 3: Cut our pop bottle open to make space for the balloon. Step 4: Put the straw through the cap and taped the balloon to the straw securely/tied a rubber band to it Step 5: Blew the balloon up and put our boat in water! Step 6: Now you have your very own boat! (: Our vehicle/boat moved forward by the air pushing out of the balloon, causing it to move forward in the water. (: Paragraph 2- Newton?s 3rd1st Law of Motion

AP Newton's Laws Review Sheet Newton's First Law (AKA Newton's Law of Inertia) ?Consider an object with no force acting on it. If it is at rest, it will remain at rest; if it is moving, it will continue to move in a straight line at a constant speed? 5 Everyday Forces Weight Fg = mg (direction is always down) Normal Force Fn (direction is always perpendicular to the surface Friction Ff = ?Fn (direction always opposes direction of motion) Applied Force FA (pushing or pulling) Tension FT (direction is always along the string or rope; tensions are equal on either side of a massless, frictionless pulley)
