Free Fall Rachel Shea Physics 131 Lab‚ QL Hasbrouck 210 Sept. 21‚ 2014 Abstract This experiment measures the study of motion by observing the force of gravity acting solely upon an object‚ and also measures reaction time. If an object is in free fall‚ the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion‚ when dropped. The main

experiment‚ the objective was to derive a second equation for the value of constant air friction force using the known values of acceleration‚ free fall acceleration (g)‚ and the various masses of the experiment. Theory: According to accepted physics‚ when an object of a larger weight pulls an object of a lesser weight there is a tension that acts between the two objects. However‚ even though the weights of the two objects are different‚ the force that each object exerts on the other is equivalent

Is it correct to say that energy from a car battery ultimately comes from fuel in the gas tank? Defend your answer. It would be correct to say that energy from a car battery comes from fuel in the gas tank and vice versa; without neither the car would not have any energy to move. Problems (p.223) 8.
