PPT-Forces Change in motion?

What causes an object to start moving stop moving or change direction UNBANLANCED FORCE What is a force A push or pull A force is described by strength and direction The strength of a force is measured in the Newton N. 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. . 11.1: Forces change motion. 11.2: Force and mass determine acceleration. 11.3 Forces act in pairs. 11.4 Forces transfer momentum. Warm-up Questions (T or F). Speed includes direction, while velocity does not. 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 . Week 2. 10/26/15 – 10/30/15. Learning Targets. Monday, October 26, 2015. I can identify a force.. I can demonstrate forces acting on an object.. I can demonstrate how unbalanced forces change the direction of an object’s motion.. 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. . Can cause a change in the motion of an object.. Tug-of-War Example:. . In the pictures above, each person is pulling with a force of 50N (. N. ewtons. ).. What will happen when the person from the first picture drops out?. 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.. Frame of reference- . a system of objects that are not moving with respect to another.. Also called a . Point of Reference. - Describing and Measuring Motion. Describing Motion. Whether or not an object is in motion depends on the reference point you choose. 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. Science Question of the Day . What causes the noise when you crack your joints?. _________________________________. _________________________________. _________________________________. Gravity . Gravity is a specific kind 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 . Review: Forces. What is a force? . Why do you think it’s important to learn about forces? What about gravity and friction?. How might an understanding of forces help you in your everyday life? .
