PPT-Forces and Inertia

Force Interaction between two objects Mutual push or pull along the line Contact or over distance Measure it in Newton lb dyne 2015 Pearson Education Inc Forces and Inertia. The unit vectors 1 2 3 B e e e are fixed in the body and directed along a convenient set of axes pass ing through the mass center G The moments of inertia of the body about t hese axes are defined as 22 xx I y z dm 22 yy I x z dm 22 zz I x Definition: . A . force. is a push or a pull in a particular direction.. How does it balance?. Textbook p. 53. You probably would be uneasy standing under Balanced Rock near Buhl, Idaho. Yet this unusual rock stays in place year after year. The rock has forces acting on it. So, . 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. . Newton’s Laws. Isaac Newton. The man, myth, the legend…while you spend your time on Facebook, Newton spent his studying the behavior of objects in MOTION.. His conclusion…anything in motion is going to follow 1 of the 3 basic . A chair will be placed in the middle of the floor. Teacher question: Are there any forces acting on this chair? . Invite . a student to gently push the chair a short distance across the floor. Ask the same teacher question . Lesson 14. February . 10. th. , 2011. DEMO TIME. Can you drop the penny in the flask by only touching the ring? . Question:. When you are standing on the train and it suddenly starts to move, what happens?. Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces. 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.. 1. st. Law of Motion. Inertia. An object will remain at rest or in constant motion unless acted upon by an unbalanced force. . “The Old Tablecloth Trick”. How does this comic relate to Inertia? . Kris . Hauser. ECE 383 / ME 442. Spring 2015. Agenda. Basic elements of simulation. Derive the . standard form. of the dynamics of an articulated robot in joint space. Also works for humans, biological systems, non-actuated mechanical systems … . Kris Hauser. CS B659: Principles of Intelligent Robot Motion. Spring . 2013. Agenda. Basic elements of simulation.

Force . 1. gives. . energy . to objects. 2. causes a. . change . in motion, such as:. . Starting. Speeding Up. Changing Direction. Stopping. Slowing Down. (Note: all of these are forms of . Dynamics I Forces & Newton’s First Law 4 Natural Forces Gravity : acts between all masses in the universe and has “infinite” range Electromagnetic (EM) Force : acts between electrically charged particles and “magnetically charged” poles Essential Question:. How do gravity, inertia, and friction affect the balance of forces?. Standard:. S8P3b. Demonstrate the effect of balanced and unbalanced forces on an object in terms of gravity, inertia, and friction.
