QUESTION: More Centripetal  Acceleration

When you Google centripetal acceleration + density, nothing really shows up.

1.  Does centripetal acceleration depend on the density of the ball at the end of the string.

2.  If so, what density equation then equals   v squared / r

Thanking you,
Brenda

ANSWER: Nope, nothing to do with it.

QUESTION: So a golf ball and a big styrofoam ball of equal weight have the same acceleration ?

Doesn't seem so ?

Thanks,
Brenda

ANSWER: Force, no, because the masses are different.  But don't confuse force with acceleration.  Acceleration in the same motion...absolutely.

QUESTION: Sorry you misunderstood,

A golf ball and a large styrofoam ball (of equal mass) being spun each on their own string via equal sources of energy,

they both have the same centripetal acceleration ?

If not then Density is in the equation.

;0)

I did not misunderstand at all.  Acceleration is the same for the same rate of speed, and you never mentioned energy before.  Energy you'd have to tell me how you're factoring that in.

Density is absolutely not a factor in acceleration, only rate of change of velocity.  That's it, it's a mathematical definition.

##### Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

##### Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
