PPT-Forces Weight (W) Units: Newtons

Weight is the force due to gravity upon an object Since the force is gravity the acceleration that is caused by the force must be the acceleration due to gravity Normal Force F N The normal force is a contact force. D. ifferent units of measurement are used to calculate:. Time. Weight. Length . Volume. Do you know what unit to use . for each type of measurement?. Units of time. Which unit?. How would we measure the time to. A . force. is a push or a pull. .. Many different forces act on objects around us all the time.. . If . the forces on the object are . balanced. , . then the object doesn’t move. . When two or more forces are acting on an object and they are not equal in size, we say the forces are . Force . A force is simply defined as a push or a pull . Forces cannot be seen. We do see or feel their effects however. Can you identify the forces at work in this situation ? . Millie . opened. the fridge and brought . Pull Force. Reaction . Normal Force. Friction. Coefficient of friction = Pull Force/ Normal Force (weight). Surface. Brick. Free Body Diagram . Since block remains on same horizontal plane, it gains no potential energy.. Apparent Weight on a Roller Coaster. WDYS??? (p406). .. .. .. WDYT???. Your weight . (does/does not) . change when you are riding a roller coaster.. If you were sitting on a scale, it . (would/would not) . Weight, Vector Components, and Friction. The Force of Gravity, Weight, and the Normal Force. The force causing all objects to accelerate toward earth’s is called the force of gravity, g. . Applying Newton’s Second Law, F=ma, we obtain the force of gravity on an object accelerating at 9.80m/s/s is called Weight, Fg=mg and is measured in Newtons, N.. Topics 5& 6. Designing With Forces . Designers often consider:. Load distribution. Directing forces to help the structure. Shaping parts to withstand forces the structure will have to resist. Problem:. Force . A force is simply defined as a push or a pull . Forces cannot be seen. We do see or feel their effects however. Can you identify the forces at work in this situation ? . Millie . opened. the fridge and brought . Define . forces and different types of forces (push or pull). Measuring . forces in Newtons. Balanced . vs unbalanced forces. Inertia- . what is it and how does it apply to Newton’s first law of motion.. 2. Review. Fluid properties. Pressure (gage and absolute). Converting pressure to pressure head. Resultant force on a horizontal, planar surface. Center of pressure. Resultant force on a vertical, rectangular surface. Warm up. Over the weekend, Carl’s Chicken sold 496 chicken sandwiches. It sold 163 salads. About how many items did Carl’s Chicken sell in all? About how many more chicken sandwiches were sold? . Net Force TEKS ( 8.6)   Science concepts. The student knows that there is a relationship between force and motion. The student is expected to: (A)   demonstrate how unbalanced forces cause changes Forces of Flight and Stability © 2011 Project Lead The Way, Inc.
