Set the length of the string to 40cm and the value should be recorded on the data table under readings. Attach the string with the pendulum to the stand and make sure it swing freely without hitting anything. Y m X When drawing the graph, we take T values to the y-axis and L values to the x-axis. We take “ T ” as the dependent variable and “L” as the independent variable. Make sure to check the functionality of the stopwatch before start. (Anon., 2015) The stand should be stable. The experiment generates more accurate results if we use metallic pendulum and a very light string. Otherwise the elasticity will affect the readings. When choosing the string make sure to check whether it’s non-elastic. Stop watch Simple pendulum Stand Meter ruler Pointer Non elastic string (Gerald & Stephen, 2001) The value differ at different points on earth depending on altitude and latitude and objects with low densities do not accelerate as rapidly due to air resistance.
The equality is true regardless of the masses or compositions of the bodies. All small bodies accelerate in a same gravitational field at the same rate relative to the center of mass if we neglect air resistance. Introduction Gravitational acceleration is the acceleration on an object cause by gravity. We modify the readings according to T2=Īccording to the equation to take the gradient and use that to calculate gravitational acceleration. We take different readings for T by changing the length of the string. In this experiment we use a simple pendulum and by oscillating it we find the oscillation time (T) of the pendulum. An acceleration on an object due to the gravity is called as gravitational acceleration. Objective is to find gravitational acceleration.
