Name ______________________________ Date ____ Mr. Carcich CP Physics Work/Power/Machines Review Be sure you understand completely the following concepts. You need to know: Work The definition and units for work. What is 1 Joule equivalent to? Work is done when a force causes an object to be displaced 1 J= How can you tell if work is being done? What are the two requirements for work? How must they be acting? (Parallel or perpendicular) Work is done only when the force is parallel to the dispalcement Object must be displaced for work to take place When will work be positive? When will work be negative? Positive: force and displacement in same direction Negative: force and displacement in different directions How can you increase the amount of work you do?

WORK, ENERGY, AND POWER Objective: 82 ? Describe the relationship between force, displacement, and work change in an object's motion is related to both force and how long it acts net force x distance = WORK WORK = the product of the NET FORCE an object and the DISTANCE through which the object is moved the heavier the load or higher something is lift, the more we do WORK IS DONE WHEN A FORCE ACTS ON AN OBJECT AND THE OBJECT MOVES IN TEH DIRECTION OF THE FORCE EXAMPLE: If we lift TWO loads up one story, we do TWICE as much WORK as we would in lifting one load the same distance because the FORCE needed to lift TWICE the weight is twice as great, and if we lift one load two stories instead of one story, we do twice as much work because the DISTANCE is twice as great

Rachael Dirr AMANDA?S HOUSE- SATURDAY EVENING AMANDA picks up her cell phone and dials EMILY?S phone number (PHONE RINGING) EMILY Hello? AMANDA Hey Em, wanna come over? I?ve got a new movie we can watch, and we can order a pizza. EMILY Umm? Sounds like fun, but you can count me out this weekend. AMANDA Come on Em, if you don?t come you?re breaking our tradition! EMILY I know, and I?m sorry, but I just don?t feel like it this weekend. I have to go now; I?ll see you at school on Monday. Bye. (CLICK OF PHONE HANGING UP) AMANDA Bye? AMANDA spends the rest of the night watching the movie alone. SCHOOL LUCH- MONDAY AFTERNOON AMANDA and EMILY are sitting at the school lunch table with a group of friends telling jokes and laughing.

Net force

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

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)
