PPT-Work, Power, and Simple Machines

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. November 24. th. -25. th. . Goal:. I will be able to explain the relationship between mass, force and distance traveled. . I will be able to describe the difference between different simple machines. . By:. Drew Harris. Simple machines. The basic machines that make up other machines are called . simple machines. . There are six of them. They are lever, pulley, wheel and axle, inclined plane, screw, and wedge. All these machines help us move things by changing the size of the force applied, the direction of the force, or both at once. . A. 5. th. Grade Smarty Pants?. Simple Machines Song. A bar that turns against . an unmoving point is called a…. Wheel and Axel. Lever. Pulley. Wedge. Video. A bar that has an inclined plane wrapped around it is called a…. Simple Machines. A simple machine has few or no moving parts.. Simple machines make work easier.. With or without a simple machine the work is the same.. Also when simple machines are combined they can make complicated bigger machines.. Simple machine is a term used to describe certain parts and pieces.. A simple machine is an apparatus that is made of a small number of pieces and permits us to use more efficiently or more comfortably mechanical energy. It helps us reduce the necessary force to perform a task.. including Finite State Machines.. Finite State MACHINES. Also known as Finite State Automata. Also known as FSM, or State . Machines. Facts about FSM, in general terms. Finite State Machines are important . A simple machine is any of the basic mechanical devices for applying a force, such as an inclined plane, wedge, or lever.. Simple machines are utilized to reduce the amount of force required to perform work, initiate or resist motion, break or split molecular bonds of solids, or keep two non-molecularly-bonded solid objects bound together.. 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. Pay attention. Simple Machines. Simple machines assist us in doing work by creating a mechanical advantage.. They . do not . change the amount of work; they lower the effort force. There are 6 types of simple machines: lever, inclined plane, pulley, wedge, screw, and wheel and axle.. 2. SIMPLE MACHINES - LEVER. A lever is a rigid bar that rotates around a fixed point called the fulcrum.. The bar may be either straight or curved.. In use, a lever has both an effort (or applied) force and a load (resistant force). . 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. 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..
