Can we experimentally measure the very weak gravitational force between two objects just like we can detect magnetic field lines by a deflecting compass.
To measure gravitational force experimentally, you can use a simple pendulum set-up or a torsion balance. Both of these methods involve measuring the amount of deflection caused by the gravitational force acting on an object.
The equipment needed to measure gravitational force includes a pendulum or torsion balance, a stopwatch or timer, a ruler or measuring tape, and a known mass to act as the object experiencing the force.
The accuracy of experimental measurements of gravitational force depends on the precision of the equipment used and the skill of the experimenter. With careful calibration and measurement techniques, the results can be quite accurate.
The measurement of gravitational force can be affected by factors such as air resistance, friction in the pendulum or torsion balance, and the accuracy of the timing and measuring equipment. Additionally, the strength of the gravitational force can vary depending on the distance between the objects and the masses of the objects.
The results of experimental measurements of gravitational force can be used to calculate the gravitational constant, which is a fundamental constant in physics. It can also be used to validate the laws of gravity and to study the effects of gravity on different objects and systems.
