Physics Review Question Unit: Mechanics Year: 1995 Question#: 54 Question: As the mass of a body increases, its gravitational force of attraction on the Earth (1 ) decreases (2 ) increases (3 ) remains the same What is this question really asking? Explanation by: Dana H (partly) [ Return to question menu ] Answer 1 decreases INCORRECT The force of gravity (the weight) is dependant on the mass of the object. w=mg ...on Earth the acceleration due to gravity g= 9.8m/s2 down. return to top Answer 2 increases CORRECT The force of gravity (the weight) is dependant on the mass of the object. w=mg ...on Earth the acceleration due to gravity g= 9.8m/s2 down. Keeping this in mind, we can argue that as the mass of on object increases, its weight (the pull of gravity) will increase too. return to top Answer 3 Remains the same INCORRECT The force of gravity (the weight) is dependant on the mass of the object. w=mg ...on Earth the acceleration due to gravity g= 9.8m/s2 down. return to top Answer 4 return to top What's this question really asking? Does the gravitational force of attraction on the Earth change as the mass changes? return to top |
