Possible Duplicate: Don’t heavier objects actually fall faster because they exert their own gravity? When true: The force pulling the "heavy" object down is greater BUT it also takes more force to ...

Let's say there are two objects.. one the size of a bowling ball weighing 10 pounds.. and the other object is the earth's moon.. they are both the same distance from the earth.. now.. wouldn't the ...

Do both heavy & light objects fall at same velocity? Isn't heavier objects have greater pull, according to law of gravitation?

$$m\frac{d^2r}{dt^2}=-G\frac{Mm}{r^2}, \qquad r(0)=R ,\qquad \dot{r}=v_0>0$$ describes the free fall of an object of mass $m$. $r(t)$ is the distance of m to the center of the earth which is $R$ ...

My eighth-grade physics teacher taught us that the equation for height ($h$) during a free fall in a vacuum is equal to the initial height ($H_0$) minus a constant ($G$, though not the $9.8$ meters ...

Please explain where my logic is wrong. a) Ignoring air, the same bowling ball will fall faster on Earth than on the Moon. b) Now, for the feather and hammer on the Moon, reverse your point of view ...

Galileo stated that objects dropped from the same height will hit the ground at the same time, that the rate of gravity is constant for all objects no matter the mass. But I think there is a flaw in ...

I know that acceleration due to gravity is independent of mass : $$a = \frac{F}{m} = G\frac{M}{r^2}$$ Meaning that a hammer and a feather fall with the same acceleration on the moon. I am confused, ...

Since Newtons laws on gravity state that the gravitational attraction between two bodies is directly proportional to their masses and inversely proportional to the square of the distance between them, ...

I read somewhere that mass affects gravity– if the mass of the objects are larger, then the force of gravity between them is larger. So, does this mean that the gravity between 2 massive objects is ...

This is a common example physics teachers use. As far as I know, it never actually holds true. There are point masses: A(light, eg. feather), B(heavy, eg. hammer) and, C(eg. the Earth). They are all ...

Debate over dinner: we read on Wikipedia that objects fall at the same speed towards Earth regardless of mass. Then we remember seeing on TV ages ago an astronaut dropping a feather and bowling ball ...

So I usually read, that the falling speed of an object towards the earth is independant of the mass of the object. Is this actually true? Shouldn`t the earth fall towards the object as well, therefore ...

According to Newton's third law of motion that states that every action has an equal and opposite reaction. So, if the Earth exerts a gravitational pull on us (people) then even we should exert a ...

I'm far from being a physics expert and figured this would be a good place to ask a beginner question that has been confusing me for some time. According to Galileo, two bodies of different masses, ...
