Graphing: Curve and Right Line

Objective: To find experience in gathering and displaying data from a simple experiment Supplies: Meter adhere, tape, and a ball is needed to carry this out experiment. Theory: The graph of function is the assortment of all purchased pairs graphing on a cartesian plane is sometimes referred to as a curve drawing. Experimental Techniques:

Position a meter stay vertically over a flat surface, for example a wall or perhaps the of a research laboratory bench. be sure the metric scale of the meter stay is on the exterior and protected the meter stick to the wall structure or lab bench with two whitening strips of masking tape. You could then take a ball as nearby the meter adhere as possible and measure a) the height fallen and b) the causing height bounces. Repeat this for 3 different levels dropped and records all data. Then you certainly will make a graph in the data. Produce at least three more measurements for every of the past three height dropped levels. Find the typical height returned for each level and record the data plus the average principles. Make a brand new graph in the average level bounced for each and every level the fact that ball was dropped. Draw a straight range best fit that features the origin by considering the standard trend of the data items measurement data. Draw that straight line as close as possible to as many data points as you can so that you have got about the amount of data factors on both sides of the directly line. Compare how well both chart predicts the heights that the ball can bounce intended for height lowered that were not tried previously. Located an untried height dropped distance on the right line then simply use the corresponding height returned from the chart as a conjecture.
