SUMMARY

The discussion focuses on the abbreviations used in the Grade 11 physics unit on Dynamics, specifically the meanings of various force notations. 'F' denotes force, with FN representing normal force, FT indicating tangential force, Fpull as pulling force, and Ff as friction force. The conversation emphasizes the importance of consulting the textbook for definitions and understanding diagrams, as standard notation can vary. Participants agree that careful reading of the material is essential for mastering these concepts.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces.
  • Familiarity with dynamics and motion principles.
  • Knowledge of reading and interpreting physics diagrams.
  • Ability to reference and utilize a physics textbook effectively.
NEXT STEPS
  • Study the definitions of forces in your physics textbook.
  • Learn about the role of normal and frictional forces in dynamics.
  • Explore the concept of tension in physics problems.
  • Practice solving dynamics problems using free-body diagrams.
USEFUL FOR

Grade 11 physics students, educators teaching dynamics, and anyone seeking to clarify the terminology and concepts related to forces in physics.

What is Fpull, FN, FT, Fa, Ff stand for in physics? I am in Grade 11 uni physics, we just started the unit today and I am a bit confused
 
Physics news on Phys.org
Dynamics is the study of force and the motion of bodies.

'F' means force.
FN probabily means a normal force. This means a force perpendicular to a surface.
FT probably means a tanget force. The force along a surface or edge.
Fpull is a pulling force.
Ff could be used to identify the force of friction.
Etc.
 
I would guess that "Ft" is "tension".

And "Fa"...

Nope, I got nothing...
 
If you have no other compelling way to label things, ofter I just resort to subscripts 'a', 'b', 'c', etc.
 
There is very little standard notation for this type of problem. The author of your book has defined all of those symbols somewhere in the vicinity of where they are used. Study very carefully any diagrams associated width the problem very likely they are defined there. The best solution for your problem is to read your book very carefully. It is not a novel do not read it like one.
