PPT-Gravity Balanced and Unbalanced

Forces amp Gravity Notes Write down the words in yellow The words in white are discussion points you may write these down but are not required Gravity Gravity is a force that pulls objects toward each other. One popular urban myth tells a story of a man who makes a wish from the top of the Empire State Building, then tosses a penny off the roof. Over 1,000 feet below, a pedestrian is hit by the speeding penny and killed. …Good luck, huh?. 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. . 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. Page 21 . of your journals. Set up a t-chart . Balanced Force. Unbalanced Force. Your definition. Your definition. On page 4 of your journals . Set up a template like the one shown (half page). Balanced Force. EQ: What changes an object’s motion?. Friction and Gravity. What happens when you jump on a sled on the side of a snow-covered hill?. What happens at the bottom of the hill?. Friction and Gravity. Why does the sled’s motion change on the side of the hill and then again at the bottom?. 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 . Forces. Presented by Kesler Science. What are balanced and unbalanced forces?. How do unbalanced forces cause a change in position, direction, and speed of an object when acted upon by unbalanced forces?. Forces. What is a force?. A force is a push or pull that causes an object to move, stop, or change direction. In . physics, . a force is anything that makes an object . accelerate. Balanced and Unbalanced Forces. . . 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 . How do balanced and unbalanced forces affect an object's motion? . Inertia. is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. . Balanced and Unbalanced Forces SC.6.P.13.3 Investigate and describe that an unbalanced force acting on an object changes its speed, or direction of motion, or both. ALSO ASSESSES: SC.6.P.12.1 Measure and graph distance versus time for an object moving at a constant speed. Interpret this relationship. Balanced or Unbalanced. Direction: Left or Right. Calculating Net Force Practice. Problem # 1. 8732N. unbalanced. Problem #2. 13. unbalanced. Problem . #3. 2380. unbalanced. Problem . #4. 25. unbalanced. 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.
