i assume that the object's mass is m Kg. and the Earth's mass is M Kg.
i want to know the kenetic of object respect to the Earth's while the object is falling .
it may be m/M or M/m or equal to 1 or 0 .
i try to understand to law of kenetic energy but it so hard of this case for me...
Ohh sorry !
Hmm , i have ever seen comparison of the K.E of object 1 to K.E of object 2 while falling down . So in this case , i want to compared with the Earth instead of object 2.
thanks for answer , just doubt !
About my thinking ! Kenetic E"
last week i am thinking about the kenetic energy of the Earth compared with the object that falling down .
I assume that it may be equal to 0 or ∞ but no why ??
How about you for this case ?
