Topic > The force of gravity explained: a practical experiment

Index IntroductionMethods, results, discussionConclusionIntroductionGravity is the force that attracts a body towards the center of the earth; a common example of gravity in action is a falling object. When the toast slides off the table, it is observed to frequently fall with the jelly facing down. As the bread falls, it accelerates, or undergoes a change in speed, toward the ground; however, friction, the resistance that one object encounters when moving over another, must be taken into account because air resistance, the frictional force that air exerts against a moving object, causes the The object slows down as it falls. The weight - the relative mass of a body that gives rise to a downward force - of the jelly on the bread can be heavy enough to significantly alter the side on which it lands when it falls because the weight of an object is known to influence the time taken to fall due to air resistance applied to the object.

It is expected that a larger amount of gelatin will cause the bread to land faster. In this experiment, the observation was tested with the amount of jelly as the independent variable, while the dependent variable was whether or not the toast fell with the jelly facing down. The control of the experiment was bread with one side marked without gelatin. If there is more jelly on the bread, the bread is more likely to fall jelly-side down. Materials 4 pieces of bread 2 oz. gelatinTriple beam scalePlastic knifePaper plateFloor paperMethods, results, discussionThe paper plate and bread were weighed on the triple beam scale and recorded. Different amounts of gelatin were spread on each slice of bread. Each slice of bread was weighed and scored again with gelatin. Each slice of bread was pushed off the table to determine whether or not it fell onto the gelatinous side for a total of three trials for each bread. No correlation was shown between the mass of the jelly and the number of times the toast fell jelly-side down. In all tests, ten times out of twelve, the toast fell with the jelly facing down. The only times the bread remained gelatinous or with the marked side facing up were the slice that contained no gelatin and the slice with 16.5 grams of gelatin. The results show that the toast fell on the jelly side in almost every test. The only exceptions to the data might be due to the different amount of force applied to the toast as it was pushed away. Another explanation may have been the uneven distribution of the gelatine on the bread, resulting in the possibility of the gelatine falling off the bread. Unlike research conducted on gravity and free fall, the heavier bread in this experiment did not affect the side of the bread on which it fell. Although the bread with more jelly may have landed slightly faster, the height was not high enough to allow the lighter bread to rotate 360 ​​degrees before landing on the ground; therefore, the frequency with which the toast lands jelly-side down does not depend on the mass of the jelly.
