Would balls of different mass roll down the pipe with different accelerations?

Answer 1

Galileo has done this already.

Answer 2

Rolling is different from sliding. Rolling involves dinetic energy of rotation which depends on moment of inertia of the body which in turn depends on the mass and radius of gyration.

Therfore the kinetic energy of rotations for different masses are different.

Therfore, balls of different mass will roll down the pipe with different speeds.

Answer 3

specific, it extremely is unusual even though it may desire to ensue. there become an outstanding-popular case indoors the suggestions some years interior the previous a pair of woman taking fertility remedies. the potential gathered her husband's sperm in a field that have been earlier used, and had no longer been precise washed. After the female become inseminated at the same time along with her husband's sperm from this field she grew to become pregnant, and found out it become twins. What a ask your self it become very just about 9 months later mutually as one twin become white and different black. They did DNA tests and found the black twin's father become the husband of a various woman utilising an same facility for fertility remedies. It become a tragic case and there become a custody conflict between the two couples, yet i will't undergo in suggestions which couple have been given to maintain the toddler.

Answer 4

mz jade, you are quite the curious mz !

as was stated, the great physicist galileo discovered that the mass of an object has NO relation to its acceleration due to gravity ! ( all objects fall at the same rate ).

the actual calculation of any object's descent was stated by isaac newton ( and is dependent only on the mass of the earth )

why this is so was only recently explained by albert einstein in the last century. ( objects follow the curvature of space and time regardless of their own size ) .

you see, your most simplest of questions took almost 3 centuries to answer ! it has deep implications in the progress of physics and i am glad you asked .

hope your question was answered ( i kept it brief ) but if you have any comments please write.

:)

Answer 5

Much more info is needed.

1) describe the physical setup
2) are they the same dimensions?
3) is air resistance considered?

You're asking for output without any input on your part!

Answer 6

Depends on the shape of the guy attached to them

Answer 7

No, not unless you take into account friction and air resistance

Answer 8

No. The same. Try it.

Answer 9

No.

Answer 10

no.
