{"Image DocumentName": "12. Gravitational The force exerted on a body due to its mass.", "Image ImageDescription": "It is one of the FUNDAMENTAL forces. The weight of a body is equal to the gravitational force acting on the body. Near the Earth\u2019s surface a body of mass 1kg in free fall (insignificant air resistance) accelerates downwards with an acceleration equal to g = 9.81 ms-2. From Newton\u2019s 2nd law: \u03a3F = m a. \u03a3F = 1 kg x 9.81 ms -1. weight = 9.81 N. In general: weight = mg.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
