    Friction Rolling
AI Thread Summary
A ball rolling on a horizontal plane experiences forces including gravity, friction, and the normal force. Friction acts opposite to the ball's velocity, generating a clockwise torque that increases its angular velocity. The center of rotation is crucial in understanding the dynamics of the ball's motion. The interaction of these forces and torques determines the ball's acceleration and rolling behavior. Understanding these principles is essential for analyzing the motion of rolling objects.

Consider a ball rolling on a horizontal plane where friction is present. The forces acting on the ball are mg, friction at the contact and the normal force. This friction acts opposite to the direction of velocity. That should provide a clockwise torque and hence increase the angular velocity of the ball. Explain.

Hi sr_philosophy! :smile:

Hint: where is the centre of rotation? :wink: and does it matter? :rolleyes:
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
