Direction of Acceleration Vector

AI Thread Summary
In circular motion, the direction of the acceleration vector is typically perpendicular to the motion, particularly in uniform circular motion. The centripetal force acts inward, causing this perpendicular acceleration. However, the question's wording could lead to confusion, as it does not specify uniform circular motion or distinguish between centripetal and net acceleration. Clarifying these terms would enhance understanding and accuracy in responses. Overall, the direction of the acceleration vector in circular motion is context-dependent.

Homework Statement



What is true about the direction the acceleration vector points in circular motion situations?

Homework Equations



a It is perpendicular to the motion.
b There is no acceleration.
c It points opposite the motion.
d It points parallel to the motion.


The Attempt at a Solution


I got a, because if the object goes in a circle and the centripedal force pulls it it, it's perpendicular. Am I right?

Centripetal perhaps? And yes, you are correct.
 
Thank you so much :) Good to know about the spelling. You learn something new every day!
 
The direction of centripetal acceleration is perpendicular to the motion .But the question asks direction of acceleration vector which may or may not be perpendicular to the motion .The direction of net acceleration vector is perpendicular only in case of uniform circular motion.

The question should either specify that it is a uniform circular motion or should ask the direction of centripetal acceleration .Only then ,the options make sense.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
