A. What is the difference detween mass andweight of an object. Will the mass andweight of an object on the earth be sameas their values on Mars? Why? |

Answer» Answer: In SCIENTIFIC contexts, MASS is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the FORCE exerted on an object by gravity. In other words, an object with a mass of 1.0 kilogram weighs approximately 9.81 NEWTONS on the surface of the Earth, which is its mass multiplied by the gravitational field strength. Thus the object's weight is less on Mars, where gravity is weaker |
