In this experiment we will do some statistical analysis, then we will apply this analysis to measuring g. If we set a sphere at a given height above the ground h, and release the sphere from rest, the sphere as mentioned The manometer in Figure 3(a) is connected to two tubes that are small enough not to appreciably disturb the flow. Explain how this works in terms of Bernoulli’s principle. (credit: Antonia Foy, Flickr). The data is in good agreement with the predicted fall time of /, where h is the height and g is the acceleration of gravity. The acceleration due to the Earth’s gravity at any height. Assume that acceleration due to gravity is -16 ft/s2. The pressure on top of the wing is therefore reduced, creating a net upward force or lift. Under gravity, acceleration is 9.8 m/s² and is denoted by g. When an object is falling freely under gravity, then the above equations would be adjusted as follows: v = u + gt; h = ut + 1/2 gt 2; V 2 = u 2 + 2gh; In the above equation, + is replaced by – if the body is thrown upwards. Conversely, a stream of water falling straight down from a faucet narrows. At different points on Earth's surface, the free fall acceleration ranges from 9.764 m/s 2 to 9.834 m/s 2 depending on altitude, latitude, and longitude.
