**Big Idea 12: Motion of Objects**A. Motion is a key characteristic of all matter that can be observed, described, and measured. B. The motion of objects can be changed by forces.**Benchmark Number & Descriptor**• SC.6.P.12.1 • Measure and graph distance versus time for an object moving at a constant speed. Interpret this relationship.**MOTION**I know the car moved because they are in different locations based on the tree (reference point). • Motion is the movement of an object. • When identifying motion, you must use a reference point. • An object that appears to stay in one place • To describe the motion of an object, you would describe how the object’s direction, distance, or both, changed relative to the reference point.**SPEED**• Rate of change of position • Calculation: • Speed = Distance Time**CONSTANT SPEED**• The speed of the moving object is always the same no matter the location. • When graphing constant speed: • Distance on y-axis • Time on x-axis • Constant speed is shown as a straight line. • When in constant motion, the slope of the line does not change.**Graphing Constant Speed**The slope of this line does not change. The distance on this graph stays the same Speed = d/t = 0/10 = 0 m/min The object is not moving. The slope of the line does not change. The change in distance for every minute on this graph is constant. Speed = d/t Speed = 2 m/min**Knowledge Check**• How can you identify if an object is in motion? • 2. What is the definition and formula of speed? • 3. By looking at a graph, how can you tell if it is representing constant speed?**Knowledge Check**• How can you identify if an object is in motion? • Find a permanent reference point. Compare before and after movements to the reference point. If the RP is in a different location from start to finish, the object has moved. • 2. What is the definition and formula of speed? • Rate of change of position • Speed = Distance/Time • 3. By looking at a graph, how can you tell if it is representing constant speed? • The slope of the line does not change at any point.
