The earth exerts a gravitational force of 0.500 N on an object. What is the mass of the object in g?
Gravitational force (weight) = (mass) times (acceleration of gravity). On or near the surface of the Earth, the acceleration of gravity is about 9.8 m/s². Within that region . . . (0.5 newton) = (mass) x (9.8 m/s²) Divide each side by 9.8m/s²: Mass = (0.5 newton) / (9.8 m/s²) Mass = 0.051 kilogram = 51 grams (rounded)
