SOS -- Questions about mass, acceleration and velocity

Click For Summary
The discussion centers on a request for help with understanding the relationships between force, momentum, angular momentum, kinetic energy, potential energy, mass, acceleration, and velocity. The original poster expresses frustration with the topic, indicating a lack of confidence in their scientific abilities. Respondents emphasize the importance of demonstrating prior attempts at solving the problem before receiving assistance. They suggest starting with fundamental equations, such as F=ma, to explore the connections between these concepts. The thread is temporarily closed for moderation, highlighting the need for adherence to forum guidelines.

Homework Statement
how force, momentum, Angular momentum, kinetic and potential energy are linked with respect to mass, acceleration and velocity
Relevant Equations
N/A
Please some one help! I am about to go stir crazy. I am really struggling to answer a the following question...describe how force, momentum, Angular momentum, kinetic and potential energy are linked with respect to mass, acceleration and velocity.

Its probably really easy but science is not my strong point so please do not judge me. Thank you in advance for any help.

According to the homework guidelines you need to show us your best attempt at solving a problem yourself.

What do you know about these quantities? Have they been covered in your physics course?
 
I would suggest starting by writing out mathematical equivalents of the various terms you are asking about. Low hanging fruit is F=ma. Define all the questions in terms of m, a, and V and see where you get to.

Welcome to PF.

As has been mentioned, you need to show your efforts to work on the problem before we can provide tutorial help. Please start a new thread in this forum and show your best efforts to start listing the relationships that you are asking about. Thank you; this thread will stay closed.

Thread 'Chain falling out of a horizontal tube onto a table'

My attempt: Initial total M.E = PE of hanging part + PE of part of chain in the tube. I've considered the table as to be at zero of PE. PE of hanging part = ##\frac{1}{2} \frac{m}{l}gh^{2}##. PE of part in the tube = ##\frac{m}{l}(l - h)gh##. Final ME = ##\frac{1}{2}\frac{m}{l}gh^{2}## + ##\frac{1}{2}\frac{m}{l}hv^{2}##. Since Initial ME = Final ME. Therefore, ##\frac{1}{2}\frac{m}{l}hv^{2}## = ##\frac{m}{l}(l-h)gh##. Solving this gives: ## v = \sqrt{2g(l-h)}##. But the answer in the book...
