PPT-U2L2 1 Unit 2 Lesson 2 Motion and Force

U2L2 2 Lesson 2 Key Question Example Consider giving a lowfriction cart a quick shove along a track When an object is moving does this mean there must be a force pushing it in the direction of its motion. Chapter 2 Section 2 Review. A. . An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.. B. . Every action has an equal and opposite reaction. . A projectile is an object upon which the only force acting is gravity. .. An . object dropped from rest is a projectile (provided that the influence of air resistance is negligible). .  . An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). . Simple version of Newton’s three laws of motion. Newton’s Laws and the Mousetrap Racecar. 3. rd. Law: “for every action there is an equal and opposite reaction”. Is more mass a good thing or a bad thing for a mousetrap racecar to go far?. 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 . Housekeeping. Newton’s . First Law of . Motion. Newton’s Second Law of . Motion. Newton’s Third Law of Motion. Glossary. Inertia. is the property of objects that makes them resist changes in their motion. So, the greater the mass of an object, the more inertia it has. For example, it takes a much . 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. . 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. 1. A system of objects that are not moving with respect to one another. Used to determine the motion of an object.. Frame of Reference. 2. If you were measuring the length of a lunch tray you would most likely label it with the following unit.. Can you change your velocity while not changing your speed?. v. F. Consider the above situation.. According to Newton . S. econd law, what must the object be doing?. It is accelerating so the velocity must be changing.. Uniform Circular motion. For an object moving on a circle at constant speed. The . speed is constant. , but the . direction is not. Acceleration is a change in velocity, but speed is constant. The change in velocity is only in its direction. Astronomy, Chapter 2. D Taylor. © 2011, 2012, 2013,2014. Gravity and Motion. 2. Introduction. Gravity. gives the Universe its structure. It is a universal force that causes all objects to pull on all other objects everywhere. Newton’s First Law. Lesson 2. 1. . What causes an object in motion to remain in motion?. friction . inertia. gravity . velocity. 1. . What causes an object in motion to remain in motion?.
