{"product_id":"cavendish-gravitational-balance-cgb001","title":"Cavendish Gravitational Balance - CGB001","description":"Demonstrates the existence of gravitational forces between masses. Measures the Universal Gravitational Constant. Verifies the Inverse Square Law for gravitational forces. This innovative apparatus, developed from the traditional Cavendish pattern, is substantially less expensive than earlier models, making the measurement of the tiny but significant Universal Gravitational Constant more accessible to students. It is precisely constructed and allows measurements of G to be made to better than 15% relative error using either the initial acceleration method or the equilibrium displacement method. \u003cbr\u003e\u003cb\u003eAdditional Info:\u003c\/b\u003e Demonstrates the existence of gravitational forces between masses.
