Abdul Muqeet AhmadPHYS 1410-NV1 Navitas PHYSICS 1 LabInstructor’s Name: Mengying ShiMotion in Free-FallJune 1 2016Partner’s Name: Huy Quang HuynhThe objective of the experiment is to examine the motion of a body in free-fall and measurethe changes in velocity with respect to acceleration.
Introduction:In this experiment, we’re going to examine the force acted on a body by the Earth’s gravitational pull. If the distance of the fall is less than the Earth’s radius, then the accelerating force due to gravity is constant and in this case it’s going to uniform. As the distance of the fall is small and the object being examined is a dense substance, we’re going to neglect air resistance as it is extremely small. So, for an object moving at constant acceleration, the velocity vs. time graph is a straight line.The formula for acceleration is:a=vv0torv=v0+atHere ‘a’ represents acceleration, ‘v’ represents the final velocity of the object, ‘v0represents the initial velocity of the object and ‘t’ represents the time taken for the object to reach the final velocity from the initial starting velocity. We can observe that the slope of a straight line is the same given at any coordinates of the graph and the graph of velocity vs. time of constant acceleration is a straight line. So, we can define the average velocity by the equation as:´v=st‘s’ is the total displacement here.
