PPT-Work, Power, and Machines

OBJ Students will determine relationships among force mass and motion OBJ Calculate amounts of work and mechanical advantage using simple machines Work When a force causes an object to move work is done. Let be the probability or fraction of time of being in state Balancing the 64258ow between state 0 and 1 yields 951 and similarly balancing the 64258ow between state 1 and 2 951 Together with the normalization 1 we get 1 ii The maximal throughp What do the F and d stand for?. What are the units for F and d?. What do the W and t stand for?. What is the unit for t?. Work is a form of energy. What is the unit for work and energy?.  . Work and Power. Extreme. Perspectives on the Future of AI. According to: . Ray . Kurzweil. Bill Joy. Doug Hofstadter. Anonymous. How plausible are these works . of science fiction? . Ray Kurzweil and “The Singularity”. - . Core . Module . 1. Equipment, Tools and Machines. Industrial Technology. Timber. Stage 5. Students learn about:. Equipment, Tools and Machines. Students learn about:. (refer to Outcomes 5.2.2, 5.4.2. Nabil. I El-. Sawalhi. Associate Professor. Construction Management. Building Plants. GENERAL CONSIDERATIONS . BULLDOZERS . SCRAPERS . GRADERS . TRACTOR SHOVELS . EXCAVATORS . TRANSPORT VEHICLES . HOISTS . Work. Work is done when a . force . (push or pull) causes an object to move in the . same direction . that the force is applied.. Formula: Work= Force x Distance . (W = F x D). If there is no movement, there is no work.. Lets see what you already know.. What is a machine? . A thing that makes work easier to do. . Can you name some simple machines? . Scissors, screws, levers, hammers, wheels and axles,...... And more complicated machines? . Why do we use machines?. Machines make doing work easier.. But they do not decrease the work that you do.. Instead, they . change the way you do work.. In general you trade more force for less distance or less force for more distance. IPC Spring . 2014. Energy, Work, Power & Machines. 1. Energy. is the ability to do work. .  . Potential energy. – stored energy or energy due to position.  . PE=m g h . m. is mass (kg). g. SPS8: Students will determine relationships among force, mass, and motion.. SPS8.e: Calculate amounts of work and mechanical advantage using simple machines.. Work. When a force causes an object to move – work is done.. The transfer of energy to an object by the application of a force that causes the object to move in the direction of the force.. work. Work is calculated by multiplying the ________ times the ________ that the object moves.. Chapter . 14, . pg . 412-435. Today’s Learning Objectives. Know the vocabulary of this chapter.. What is the two-pronged test to see if something qualifies as work?. Solve and calculate problems about work.. Chapter 6 Work and Machines A. Work Work transfer of energy through motion force exerted through a distance W = Fd Distance must be in direction of force! W : work (J) F : force (N) d : distance (m) Work, Power, and Machines Physical Science Chapter 13 Section 1 Work Occurs when a force causes an object to change its motion or position. Calculated by multiplying the force by the distance over which the force is applied.
