brotherbobby replied to the thread High School Deriving the "third" kinematic equation using graphs.Yes, am afraid I entirely forgot about that thread. True, you'd need some algebra but that can be readily done with equations (1) and... -
brotherbobby posted the thread High School Deriving the "third" kinematic equation using graphs in Classical Physics.Problem Statement : For a particle moving in one dimension along the ##x## axis with constant acceleration ##a_0## (see figure...

brotherbobby replied to the thread Undergrad Curl of velocity vector in rotational motion.Yes I agree with the second sentence of yours. It is the first that is more interesting. Let me write it again, despite being...

brotherbobby replied to the thread Undergrad Curl of velocity vector in rotational motion.Thank you, and a bit silly on my part. My derivation up there in post#1 remains the same even if the the angular velocity vector...

brotherbobby replied to the thread Undergrad Curl of velocity vector in rotational motion.Space. So if the angular velocity of the body varies with time, say ##\vec\omega(t)##, I have the following two questions. The first...

Attempt : I draw the diagram of the problem to the right. A circular plate of radius ##a## rotates with an angular velocity ##\vec\omega...
