Free fall and the acceleration due to gravity Problem/Question: How do you measure the acceleration of a falling object? Hypothesis: by measuring velocities of a falling ball then applying the data into equations numerous times‚ the results should approach to the acceleration. Variables: A: Independent Velocity B:Dependant Acceleration C:Constant Distance (photo gates) Materials: Photo gates‚ Clay ball‚ Photo gates machine.

Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts

Experiment 1: Free Fall - Determining the acceleration of gravity Prior to Lab: Derive the numbered equations (Equations 1‚ 2 and 3) in the lab instructions using the definitions of velocity and acceleration (a=dv/dt and v=dy/dt). Object: The object of this experiment is to determine the value of the acceleration of gravity by measuring the rate of acceleration of a freely falling object. In addition‚ one will be able to compare theory with experiment for constantly accelerated motion. Discussion:

Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity‚ g‚ was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317‚ which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop

Revenues and operating earnings increased 12% and 6% respectively comparing to year 1981. In ten years‚ the company raised its revenues‚ net income‚ cash and assets more than 2 times. It`s worth to mention that AT&T was able to reduce its total outstanding debt by $ 725 mil and at year-end‚ the company`s debt ratio stood 42.3% down from 46.7% in 1980. In addition‚ AT&T

Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their

of this experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration‚ which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment‚ a vertical stand with an electromagnet at the top for holding and then releasing of the falling body‚ called the plummet. The plummet falls between

A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment‚ enabling the system of masses to move without an applied force or a frictional force. This experiment will measure the motion of an

physics honors Acceleration due to gravity by picket fence method Varun Kumar Pd 7 Saumya Kapoor & Tonia Li 9/26/2014 INTRODUCTION Acceleration is the increase or decrease in velocity. It can also be described as the rate of change in velocity. Acceleration is represented by the formula: . In this experiment we look at a specific type of acceleration‚ Free-Fall. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important
