Question

the centripetal force on an object in circular motion is?

Answer 1

The force that acts towards the center of the circular path taken by the object. This force also keeps the object in circular motion. Without that force the object would drift in a straight line with constant velocity.

Answer 2

When you drive on a curved road, you are in circular motion. What is the centripetal force?.........FRICTION. That keeps your car from drifting out of the road in a straight line to possible death.

Answer 3

Mathematically, centripetal force is:
\[F = \frac{mv^2}{r} = m\omega^2r\]

Or if you want to keep it as a vector:

\[\vec{F} = \frac{-mv^2\hat{\vec{r}}}{r} = -m\omega^2\vec{r}\]

where \[\hat{\vec{r}}\] is the unit vector in the radial direction.

Answer 4

Well, on the big bang theory, Leonard was able to put an olive into a glass with centripetal force. If you take a look what do you think it is?
