PPT-Forces, Motion and Inertia

Newtons Laws Isaac Newton The man myth the legendwhile you spend your time on Facebook Newton spent his studying the behavior of objects in MOTION His conclusionanything in motion is going to follow 1 of the 3 basic . 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. . 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. 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. Forces. Forces. Forces have . Magnitude . and . Direction. . We represent these in diagrams with arrows. . Larger the force the bigger the arrow. . 50N in Each direction. Forces and Motion. When we look at a diagram we can figure out the sum of 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.. University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Inclined Plane Experiment. Although it may seem daunting, rotational motion is fairly straightforward. In many ways it is analogous to the linear motion that you have studied previously. Rotational motion can be examined using the same principles of energy and momentum conservation that you have used previously. The equations that accompany these laws take a slightly different form, but at their root, they are based on the same physical principles. So begins your three part study of rotational motion which includes this lab, the rotating bar in . 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? . Force. - a . push. or . pull . A . 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 . Science Question of the Day . What causes the noise when you crack your joints?. Gravity . Gravity is a specific kind of force.. A force is simply the push or a pull on an object.. Can you think of some examples of pushes and pulls on objects?. 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.
