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

Learner Guide for Cambridge O Level Physics ? Cambridge International Examinations 2012 Learner Guide for Cambridge O Level Physics How to use this guide The guide describes what you need to know about your O level Physics examination. It will help you to plan your revision programme for the written examinations and will explain what we are looking for in the answers you write. It can also be used to help you to revise by using the tick boxes in Section 4 ?What you need to know', to check what you know and which topic areas of Physics you have covered. The guide contains the following sections: Section 1: How will you be tested? This section will give you information about the theory and practical examination papers. Section 2: Examination tips

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)

CHAPTER 6 REVIEW NAME_________________________________________ 1) Can work be done on a system if there is no motion? A) Yes, if an outside force is provided. B) Yes, since motion is only relative. C) No, since a system which is not moving has no energy. D) No, because of the way work is defined. Answer: D Diff: 1 Type: BI Var: 1 Page Ref: Sec. 6.1 3) If you push twice as hard against a stationary brick wall, the amount of work you do A) doubles. B) is cut in half. C) remains constant but non-zero. D) remains constant at zero. Answer: D Diff: 1 Type: BI Var: 1 Page Ref: Sec. 6.1
