Uniform Circular Motion Displacement

AI Thread Summary
In uniform circular motion, displacement is not constant as it changes with the position of the object. Velocity is also not constant due to the continuous change in direction, despite speed remaining constant. Acceleration is always directed towards the center of the circle, making its direction change as the object moves, which contradicts the idea of constant direction. The magnitude of acceleration remains constant, but its direction does not. Therefore, the assertion that acceleration direction is constant is incorrect.

In uniform circular motion:
True False Displacement is constant.
True False Velocity is constant.
True False Acceleration and velocity are perpendicular.
True False Speed is constant.
True False Accleration direction is constant.
True False Acceleration magnitude is constant.


My answers are in bold, the computer says its wrong, can anyone steer me in the right direction?

Thanks :)

Acceleration direction is constant ?

oh, is that the only one i got wrong? i know I am close, the thing doesn't tell me what is wrong/right tho.
 
Acceleration is always towards the center of the circle, so its direction is changing as the body moves along the circular path

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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

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...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
