Do objects with different masses fall at different rates?

the only thing that leads to the misconception that heavier things fall faster is most likely due to air resistance. In a vacuum, all objects fall under the same acceleration/gravity.

Ummm.... relativity doesn't have anything to do with it.\n\nBoth objects, regardless of their mass, are pulled toward Earth by the exact same gravitational force, and therefor are accelerated in exactly the same way (9.8 m/s^2) Thus they fall at the same rate.

dba_gregg has missed the point that both are same weight\n\nThe moment of Inertia of a hollow sphere  is 1.6 times greater than the solid sphere and so it rolls down slowly.\n\nThe speed of solid sphere will be 1.09 times the speed of hollow sphere.

same mass, same weight

g ia actually 9.80m/s^2 for free falling bodies. And about the clocks pendulum, if you see it in a technical point of view, the answer would be NO; but it also depends on how the clock is dropped. The point is both the clock and the pendulum would freefall (9.80). Theoretically it's possible for the pendulum to swing but I can't explain it.

I know the following two ways:\n\n1) Force on a body  is directly proportional  to the product of it's mass and acceleration, F=K*m * a(k=constant).The units are so chosen so that K=1.\n Your's is also correct but it is limited to free falling bodies, where a=g=9.8 m/s^2.\n2)Force is directly proportional to the rate of change of momentum.\nF=k*(change in momentum,p)/t=K*p/t. Again K=1 for same reason..\nBoth are related as p=m(v-u)/t=m*a.\nv=final velocity, u= initial velocity.\nhope it helps.

Your question is very awkwardly worded. I assume you're talking about mass, not weight. Mass is the amount of matter in something. Weight is force that gravity "pulls" on it. With the same object, mass is always constant. Weight changes if you're on the moon, or in outer space.\n\nAs for its gravity, do you mean the Earth's pull on it, or the gravity field the object projects? If it's the former, then yes. That's how weight is defined. All things fall at the same rate, however. As for the latter, then, yes, the mass of an object dictates how big the gravity field around it is. The Sun projects a huge gravitational well, while a penny projects next to nothing.

The others gave the correct answer overall, but got the details wrong.  All objects accelerate, when dropped in free fall near the surface of the earth, at 9.8 meters/second/second (not 9.8 inches/s or 9.8 miles/hour).\nThe reason heavier object don't fall faster is that, although they have more weight, i.e. more gravity pulling on them, they also have more mass, i.e. more "inertia", which is the resistance of objects to being accelerated.  The two things exactly cancel out; isn't that convenient?  \n\nBtw, the reason why they cancel out, that is, the reason why the mass that shows up in the formulas for gravity is the same quantity that shows up as inertia in Newton's laws, was not fully solved until Einstein, but the fact that they do was known to Galileo.

they would fall at the same time unless there is a force acting upon one of the weight...

No. As a simple example, imagine a snake curled into a perfect circle. Its center of gravity is in the center of the cirlcle the snake forms, which is within the empty hole in the middle.\n\nCenter of gravity is the average location of an object's weight.

d is the most correct answer, yes.  \n\nHowever keep in mind that despite g being the "gravitational constant", acceleration caused by gravity DOES change depending on the the distance from the earth.  When we're talking about the difference of a table, there is practically no difference, however keep in mind that it does change.

If they were in the same place and time, 'same' mathematically, they would fall at same speed.\n\nIf they were in different places or time, the forces exert on them may be different e.g. the moon which cause tides, and the gravitational acceleration 'g' is different from place to place.\n\nMy answer is different, coz' I am not a physicist but an engineer. I take everything into account. Of course, there are many forces beside gravitation and air resistant.\n\n"No air resistant" doesn't mean that there is only gravity. Besides, gravity different from place to place.

All objects accelerate downward at a rate of 9.8 m/s/s.  If the object falls 2.6 m, at that rate, it would it the ground in approximately .53 seconds at a speed of 5.2m/s. To calculate it falls approx. 4.9m the first second then continues to speed up at a rate of 9.8m/s/s after that.  Since 4.9m is farther than the distance fallen, divide 2.6 by 4.9 and get the time taken to fall.  Take that answer and multiply that by the constant rate of acceleration to get 5.2m/s

The amswer would actually depend on what the diameter of the hoop is with respect to the moment of intertia of the sphere is.  If the hoop diamter is large and most of the mass is concentrated farther from the center of the hoop then the hoop will have more angular inertia than the sphere.  If, on the other hand, the hoop has a small diameter and is a long cylinder, then the sphere will have a higher moment of angular intertia.

It depends on where you are doing the experiment. It is a universal law that all objects fall with the same acceleration in a gravitational field regardless of their mass thus reaching the ground together if they are released from the same height but things like air resistance may change things dramatically causing the feather to fall much more slowly than for example hammer.

it is called terminal velocity, at one point no matter the mass, size or shape of an object everything will reach an equilibrium between the gravitational force pulling the object down to earth and the friction the atmosphere causes to slow the fall. If dropped high enough the rate of fall will be constant for any object, the best point to illustrate this is when parashooters all jump at different intervals but all reach a point where they are all falling at the same velocity and time.

In the absence of friction, they would fall at exactly the same rate. In the real world, assuming the balls are the same size (which means the lighter ball is less dense) the heavier ball would be faster, because the drag would be similar but the driving force (the weight) would be different.\n\nThe reason they'd travel at the same speed when friction is neglected, is exactly the same reason they free-fall at the same speed; gravitational acceleration is uniform. Placing them on a ramp (or roller coaster track) simply dilutes the effect based on the sine of the angle to horizontal.
