PPT-FORCES AND STRUCTURES Force

the influence that tends to change the speed and direction of a stationary or a moving body  External Forces Internal Forces There are 3 types of Internal forces 1 Compression 2 Tension. Forces act on you all the time. . If . you surf, you can feel many forces pushing and pulling you in different directions. . Gravity . always pulls you down, towards planet Earth. . This . force can be balanced by the support of the surfboard acting upwards. . Rate Yourself. 4 = . Explain real world situations using academic voc. . a. nd Newton’s laws.. 3 . = . Investigate and describe types of forces. Differentiate between mass and weight.. 2 . = . Describe the relationship between distance, mass, and gravitational force.. 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 . Here’s Tim & Mobey on Force. Brainpop. Suppose I asked you to move a heavy desk in the classroom. How would you move it? . hmmmmmmmmmmm...... You might get on one side of the desk and start pushing, Or you might grab the legs and start pulling. . Robert Strawn. Compiled 10/16/11. A force is any push or pull that one object exerts on . another that causes a change in motion, direction, or shape.. The unit for force is the Newton (N) and is equal to . Objectives. To introduce a truss-structure system. To define truss. To demonstrate the types of trusses . 6 - . 3. Introduction. For the equilibrium of structures . which are . made . up . of several connected parts, the . . . Example:. What is a force? . a) Strong . nuclear . force. b) Electromagnetic force. c) Weak force. d) Gravity.. EXAMPLE? an atom . #2) There are four forces that hold all matter together. 3) Gravitational forces . Standards. SPS8. Students will determine relationships among force, mass and motion. b. Apply Newton’s three laws to everyday situations by explaining the following:. Inertia. Relationship between force, mass and acceleration. Forces of Flight and Stability © 2011 Project Lead The Way, Inc. Aerospace Engineering Thrust Lift Drag Weight Forces on an Aircraft Four forces on an aircraft in flight: Weight: G ravitational attraction of the Earth Forces and Newton’s Laws SP1. Students will analyze the relationships between force, mass, gravity, and the motion of objects. d. Measure and calculate the magnitude of frictional forces and Newton’s three Laws of Motion. Review: Ideas about Friction. What is friction and how does it work? . Are there bumps anywhere else besides . the surface an object moves across?. Give an example of friction from your everyday life. .
