    Curves Friction
AI Thread Summary
When a car navigates a curve, the direction of friction is crucial for understanding its motion. Friction acts inward toward the center of the circle when the car is moving at maximum speed, providing the necessary centripetal force to maintain the turn. Conversely, at minimum speed, friction may point outward, as the car's inertia could cause it to slide outward. The relationship between speed and friction direction highlights the dynamics of circular motion. Understanding these concepts is essential for analyzing the forces at play in curved motion.

Homework Statement



If a car goes around a curve, which direction is its friction? Pointed towards the circle or outwards? Explain please. Thanks in advance.

That depends. Think about what happens when the friction is pointed inward in relation to the car's maximum and minimum velocities. Which way would the friction point if the car is moving at a maximum speed? At a minimum speed?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
