And have more tests will be better to confirm the results, if each personal do the ten times, then compare the each result, more tests is help to reduce errors. Change the yellow plastic ball to an iron ball or other heavier ball will be much decreases the effect from air resistance. Set a constant height will be better than use hands to drops the ball. Air resistance and height is just relatively constant are the most reasons. The error make the result with forecast has a large gap.
In the conclusion, this lab seems to didn’t have generated strong support for the theories and hypothesis that g = CACM/so. Conclusion The experiment is to calculate the acceleration of gravity using the Smart Timers. The data result with prediction has about 47. Also the smart line connect line data transmission time will be effect the result, but this time is almost negligible, and under the present conditions, it is no way to improve that much. Acceleration is a measure of that rate of change - it tells you how many meters per second the velocity of an object changes by. Use hand to start drop the ball is hard to constant the height, here will have some error, and plastic ball may too light, it is susceptible to get effect by the air resistance. An acceleration is a change in the velocity of an object over time.
rised accelerated expansion of the very early Universe known as inflation is. The most likely cause is air resistance and height not content. ter described by the standard model of particle physics, but 80 years after. Error Analysis The result has a considerable error with prediction. Shorten the connect line both between the Photostat and smart timers, and pad and smart timers. The new hypothesis need to make sure the ball is drop from the same height, use hands to begin the drops will be have too much error, choose a heavier ball, to reduce the impact of air resistance. It has a considerable error with prediction. (Throw out an extremely large or small value) The result have an anomalies, it’s much bigger than the prediction that g CACM/so. The data also show the average value of time and “g”. Do this 10 times and take an Data The following chart details the ten times trials of the experiment and includes an average of the ten times trials. A gravitational redshift can also equivalently be interpreted as gravitational time dilation at the source of the radiation: if two oscillators (producing electromagnetic radiation) are operating at different gravitational potentials, the oscillator at the higher gravitational potential (farther from the attracting body) will seem to ‘tick’ faster that is, when observed from the same location, it will have a higher measured frequency than the oscillator at the lower gravitational potential (closer to the attracting body).After pressing “3” start/stop button twice until a “star” appears on the screen, release the yellow plastic ball and measure the time it takes to fall. Gravitational redshift can be interpreted as a consequence of the equivalence principle (that gravity and acceleration are equivalent and the redshift is caused by the Doppler effect) or as a consequence of the mass-energy equivalence and conservation of energy ('falling' photons gain energy), though there are numerous subtleties that complicate a rigorous derivation.

The effect was first described by Einstein in 1907, eight years before his publication of the full theory of relativity. Indian Institute of Tropical Meteorology, Pune 411 008, India. The opposite effect, whereby photons (seem to) gain energy when travelling into a gravitational well, is known as a gravitational blueshift. The formula used to calculate Gexp was: G exp sin (1.56) (a 1 +a 2 )/2.
This loss of energy corresponds to a decrease in the wave frequency and increase in the wavelength, known as a redshift. Since the force of friction acts with the force of gravity on the way up the ramp and against it on the way down, the average of the two accelerations will be taken to equate our experimental value of acceleration due to gravity. In physics and general relativity, gravitational redshift (known as Einstein shift in older literature ) is the phenomenon that electromagnetic waves or photons travelling out of a gravitational well (seem to) lose energy. The effect is greatly exaggerated in this diagram. Theory: In its simplest form, Newton's law of force relates the amount of. In this laboratory we will investigate the acceleration due to the force of gravity. Accelerations are always caused by forces. The gravitational redshift of a light wave as it moves upwards against a gravitational field (produced by the yellow star below). The Acceleration Due to Gravity Introduction: Acceleration is defined as the rate at which the velocity of a moving object changes with time.
