Physics Lab: Measuring the acceleration due to gravity . Objective: to determine the acceleration due to gravity near the earth's surface by three different methods. Theory: We all know that gravity makes things fall. But just what is gravity ? Sir Isaac Newton tried to give operational meaning to the idea of gravity by seeking out the laws according to which it acts. Bodies near the earth fall toward it with a certain acceleration due to the gravitational attraction of the earth. How can the earth make a body at a distance fall toward it? How is the gravitational force transmitted? Has the acceleration due to gravity always stayed the same? These and many other questions about gravity have yet to be answered satisfactorily. In doing this lab, you will become more familiar with the effects of gravity by finding the acceleration due to gravity experimentally.

Record on the results table.
