* GRAPHS ** OBJECTIVES 1. Describe the motion of an object using graphs 2. Interpret different types of motions graphs 3. Appreciate the importance of graphs ** CONTENT A graph is a visual representation of lines that shows how to two measurements are related to each other Graphs are usually measured with a graphing paper, we can use graphs to find the position of an object, when a graph is plotted by distance travel, the graph can be called distance-time graph, if its displacement, its called a displacement time graph If a graph represents the velocity, its called a velocity-time graph. remember that the slope of a graph represents the motion. In a graph, we use a partion (?) system, where we use the x and y axis, we call the horizontal line as the x axis, while the vertical line is called the y axis The slop is the one that connects the different kinds of dots represented. *** TYPES Position (displacement) vs time SLOPE of position-time graph = velocity over that interval of time The steeper the slope, the higher the speed or velocity **** For the distance(?): If the slope is diagonal, it is moving on a constant speed, if its curvy but goinig up, its acceletrating, if the line is going from up to down on a curve, is slowing down, if the line is horizontal, its stationary, if its diagonal going downward, its returning to its original position. if its slowly going up, its steady. **** For the velocity: you can describe the acceleration for the object, if the slope is going diagonal going up, it is accelerating, a positive acceleration, if its flat, the acceleration is 0, moving in constant velocity, but if it is diagonal going down, it is negative acceleration, meaning its slowing down. But what if its a number..? You have to find out the value of the velocity and the time before you can plant anything to the graph. **** EPILLOUGE In a graph, or motion graph, you can compute for the average speed or velocity.
