# An Analysis of Gravity and Galileo's Theory of Acceleration in Physics

The purpose of this lab was to find that gravity of Earth is indeed 98 mss theThe theory according to Galileo is that two objects have the same accelerationif dropped from the same height will land at the same time at the speed of 98 mss aslong as there is no air resistance To have an understanding Galileos theory ofacceleration certain terms and equations must be known Acceleration is defined asthe change in velocity divided by the time interval which the change of velocity wasmeasured Velocity is defined as the change of position distance divided by the timeinterval that the position was measured byThe most basic formula used in this lab and in most of physics is the formulafor velocity this formula is defined as velocity change in distance divided by thechange in time v dt The basic metric units for this equation will be ms Another formula used is the formula used to find acceleration this equation is asfollows acceleration change of velocity divided by the change in time a vt The basic metric unit used with this equation are mssGravitys most common law for gravity is known as the constant accelerationof force on any objects no matter what the size or shape only if there is no windThe first step in this lab is to take the ticker timer the ticker tape and theobject being tested and put these objects nearby When cutting the ticker tape makesure to cut a long enough piece so that it will touch the ground when at the height itwill be dropped at Put the ticker tape into the timer making sure there is carbonpaper on the timer to make the marks Then tape the object to the ticker tape and makesure it is secured Once these steps have been completed drop the object NoteThere should be two objects in this lab a heavy and a heavier On lab partner
