Place the glass tube directly underneath the electromagnet, leaving space. Why cannot aeroplanes be used to go into outer space?Īns: A minimum velocity is required to escape from earth’s gravitational force, called escape velocity. Set up the apparatus by attaching the electromagnet to the top of a tall clamp stand. We investigate a variety of variables, including displacement, angle, damping, bob mass, and others. The simple pendulum experiment is used in this report to determine an approximate of 'g' (gravity). Why do we say that unit of weight is Newton?Īns: Weight is the force due to the mass acting downwards. Acceleration due to gravity experiment using a pendulum lab report. So, acceleration due to gravity is more at the poles. Poles are closer to the centre than the equator. Where is acceleration due to gravity is maximum?Īns: Acceleration due to gravity is inversely proportional to the square of the distance between the centre and the surface. The most frequently asked questions about acceleration due to gravity are answered here: Mass is a scalar, and weight is a vector. Mass is the measure of amount of substance present in an object, whereas weight is the force due to gravity on it. The same sort of analysis is used later in the. \(g\) decreases with an increase in depth below the surface.ĭ. determine velocity as a function of position, eventually leading to the gravitational acceleration. \(g\) decreases with an increase in height above the surface.Ĭ. Gravitational force on the object of mass \(m,\)Ĭombining them, \(F \propto \frac.\) All the freefalling objects fall towards earth with this acceleration.ī. Objective: In this lab, you will measure g. Let us consider the mass of earth as \(M\) and that of an object is \(m.\) Period: Physical Science Lab: Measuring and Calculating the Acceleration due to Gravity on Earth. inversely proportional to the square of the distance \(d\) between their centres
directly proportional to the product of their masses, and
#Finding acceleration due to gravity lab software#
Hardware and software prepared for the experiment are sufficient to. When acceleration is constant, the following equations may be used: 02.
We basically measured the period of the pendulum and then calculated. The universal law of gravitation states that two bodies are attracted to each other by a force which is- After repeated experiments, value of gravitational acceleration was found to be 9.805 m/s2. Once velocities are known at definite times, we can find the average acceleration by using the definition t v a. Lab report - determining the acceleration due to gravity by using a simple pendulum.
