but how can it affect the gravitational force bcz what ever caln mistake you told they doesn't affect the it .See the gravitation formula it doesn't depend on centripetal acceleration nor on speed of earth.And I have caled again F= m.a = 6E+24 kg * 0.001 m/s2 = 6E+21 N
Its again aroung 10^21N...
yaa you are right ,,Back to the original question, the amount of force required depends on how long one plans to take accelerating or decelerating. Earth masses ~6E+24 kg and there's roughly ~3E+7 seconds in a year. Braking by 30 km/s over 1 year requires deceleration at 3E+4/3E+7 = 0.001 m/s2...
It got to do with density, bcz density is = mass per unit volume so when we talk about an sphere it got an uniform density at each point bcz its mass is distributed in an uniform manner but when we talk about Earth its didn't got same mass at each point so it's density is not uniform in this way...
I asked same qun to the mit walter lewin and he told me that its an centripetal force so its doesn't move Earth towards moon It keeps Earth in its path ..
Thank you for your reply but can you please explain me how its possible when Earth got the attraction force between Earth and moon is this much so why its not moving towards moon??
Dear Sir,
My name is Ashish R. Sai I am from India.I just appeared for 11th std.A few days ago I went through Gravitation.I completed my assignment.After completing assignments,I tried to find the gravitation between the moon and earth. During this i got a few doubts in this...
