Weight refers to the force of gravity acting on a mass. we often calculate the weight of an object by multiplying its mass by the local acceleration due to gravity. the value of gravitational acceleration on the surface of mars is 0.377 times that on earth. if your mass is 85 kg, your weight on earth is 830 n (m × g = 85 kg × 9.8 m/s² = 830 n). what would be your approximate mass and weight on mars?
