Answer:
1.Ans:Because the downward force on an object is equal to its mass multiplied by g, heavier objects have a greater downward force. Heavier objects, however, also have more inertia, which means they resist moving more than lighter objects do, and so heaver objects need more force to get them going at the same rate.
2.Ans: Mass is the actual amount of material contained in a body and is measured is kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg, The mass is independent of everything but weight is dependent on the gravitational force of different bodies.
3.Ans:Weight = Mass x Acceleration of gravity. So if an object has a mass of 20 kg, then its weight will be 20 kg x 9.80665 m/sec^2 = 196.133 Newtons.
4.Ans:No, the value of g is different at different places on the surface of earth. The shape of the earth is not exactly spherical, it is flattened at the poles and is bulging out at the equator. Due to which the radius of the earth is smaller at poles and is larger at equator.
