Force Of Gravity Lab Report

Any object that fall to the earth have a constant acceleration due to gravity of -9.80 m/s^2 if air resistance is ignored.
If an object is small and have a reasonable mass, we can predict the final velocity of the object and the time of fall, since smaller objects with smaller mass have less air resistance.
Objects with smaller masses have less air resistance because their velocities are smaller.
Objects with larger masses, on the other hand, will have more air resistance because their velocities will the larger and will need a larger force to go downwards.
Air resistance of an object is affected by its mass, the total surface area that is exposed by the air resistance, and how fast an object is falling.
When an object is falling, the force diagram will be represented by the force of air of an object pointing upwards and the force of gravity pointing downwards. But the value of the force of air and the force of gravity will not be the same in the beginning of the fall since the objects did not reach the terminal velocity.
In this lab, we alter the number of the coffee filter we use, so we could make a relationship between the masses of an object and their average velocity and prove the theory about the relationship between the mass of an object and the average velocity.
This was done by using different numbers of coffee filters and analysing the data of the curved graph using the GO-Motion detector.

In table 1, we can clearly see that the higher the mass of an object is, the higher the average velocity is. If we have one coffee filter with the mass of 1.26 grams, the average velocity is -.506 m/s, and if we have 5 coffee filters with the mass of 6.94 grams, the average velocity is -1.12
