Gravity lab hole 63/21/2023 ![]() ![]() With regard to the cut-out of the crescent moon, emphasize that the CG does not have to be at a point where there is mass.Īpplications: A method of locating approximately the balance point of an object. ![]() Finding the CG of a state cut-out is entertaining but not terribly useful! When using something like the cut-out of the state of Indiana, for example, point out that this is the center of gravity of the state only if it were of uniform thickness and density, which it isnt. So when the suspended lamina come to rest, the CG must be directly below the suspension point, as determined by the chalk line. The ratio of acceleration due to gravity on them will be. Make holes at the corners of a lamina then attach the lamina to the pivot mounted on the wall in order to swing freely with the paper side facing outwards. Lab report : Center of gravity Measurements and testing Aim. Medium View solution > Two planets have radii r 1 and r 2 and their densities are 1 and 2, respectively. View Lab Report - Centre of gravity Lab report from DDBA 8510 at Walden University. For example, a pendulum always returns to this position when it finally comes to rest. The centre of the hole is at R/2 from the centre of the original disc.Locate the centre of gravity of the resulting flat body. Why does it hang straight down? Show that in equilibrium the center of gravity is always located below the suspension point. Suggestions for Presentation: Begin by showing the students a mass suspended from a string. Where the two chalk lines cross is the center of gravity. Repeat, using another hole to suspend the object from. The center of gravity is along this line. When it comes to complete rest, carefully draw a chalk line coincident with the hanging string. Fill the bottle with water, you can dye the water in order to see it better. Put a piece of tape on each of the two holes. Where the lines cross is the center of gravity of the object.ĭirections: Choose one of the objects and suspend it from a predrilled hole. Put two small holes (about the diameter of the lead in a pencil) on one side of the bottle, one near the bottom and the other about the middle of the bottle. A hanging weight suspended from the same point determines the downward direction, the line of which is marked by chalk. A variety of wooden shapes (of uniform thickness and density) is suspended from two or more points in succession.
