What is the difference between mass and weight of an object. Will the mass and weight of an object on the earth be same as their values on Mars? Why?b. What are (i) free fall, (ii) acceleration due to gravity (iii) escape velocity (iv) centripetal force ?c. Write the three laws given by Kepler. How did they help Newton to arrive at the inverse SQUARE law of gravity?d. A stone thrown vertically UPWARDS with initial velocity u reaches a height ‘h’ before coming down. Show that the time taken to go up is same as the time taken to come down.e. If the value of g suddenly becomes TWICE its value, it will become two times more difficult to pull a heavy object along the floor. Why?ANSWER:a. Difference between mass and weight of an object is as follows: S. No. Mass Weight1. Mass is the amount of matter contained in a body. Weight is the force exerted on a body due to the gravitational pull of another body such as Earth, the sun and the moon.2. Mass is an intrinsic property of a body. Weight is an EXTRINSIC property of a body.3. Mass is the measure of inertia. Weight is the measure of force.4. The mass of a body remains the same everywhere in the universe. The weight of a body depends on the local acceleration due to gravity where it is placed.5. The mass of a body cannot be zero. The weight of a body can be zero.6. The SI unit of mass is kilogram (kg). Since weight is a force, its SI unit is newton (N).
