Gravitational experiments are scientific investigations designed to understand the force of gravity and its effects on objects. These experiments often involve measuring how objects fall, the acceleration due to gravity, or how mass influences gravitational attraction. Famous experiments include those conducted by Galileo and Isaac Newton, which laid the groundwork for our understanding of gravitational laws. In modern times, gravitational experiments can also involve advanced technology, such as satellites and particle accelerators. These tools help scientists study gravity in different contexts, including its role in the universe, the behavior of black holes, and the effects of gravity on time, as described by Einstein's theory of relativity.
