When G was first measured by Henry Cavendish, newspapers of the time hailed his experiment as the “weighing Earth experiment.” Why?
Einstein concluded that gravity is the warping of the geometry of space-time based on the presence of matter. He published this theory—known as the general theory of relativity—in 1915. Einstein based the theory entirely on mathematics. He suggested a way of putting it to the test. He knew that the sun has a strong gravitational field. Its mass (about 1.99 × 10 30 kilograms) should not only affect the orbits of its planets but anything nearby. According to relativity, the sun’s gravitational field should bend light traveling to Earth from distant stars.
Explain this in simpler terms.
A cube of tin with sides of length 2.8 m is transported to the surface of Mars. What is the weight of this cube on Mars? Express this quantity in units of lbf. The specific gravity of tin is 7.28. Gravitational acceleration on Mars is 0.38 G

He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?arrow_forward
