Facts I need to learn in Physics besides the formula

Click For Summary
SUMMARY

This discussion focuses on understanding fundamental concepts in physics, specifically free fall, acceleration, and friction. The user highlights the relationship between an object's weight and friction, as well as the distinction between velocity and acceleration. For those seeking structured learning, Khan Academy is recommended as a valuable resource for introductory physics material.

PREREQUISITES
  • Basic understanding of Newton's laws of motion
  • Familiarity with the concepts of velocity and acceleration
  • Knowledge of frictional forces and their dependence on mass
  • Ability to interpret and derive physics formulas
NEXT STEPS
  • Explore the principles of free fall and gravitational acceleration
  • Study the effects of mass on frictional force using the formula F_friction = μ * N
  • Learn about the difference between instantaneous and average acceleration
  • Review online resources on introductory physics, particularly on Khan Academy
USEFUL FOR

This discussion is beneficial for students new to physics, educators seeking teaching resources, and anyone interested in grasping the foundational concepts of motion and forces.

Homework Statement



I would want to know how free fall, acceleration and friction works ?
I mean it like there is a greater friction when an object is heavier
or an object is possible to have zero velocity but nonzero accelaration.
I need those kinds of things to study :D

Homework Equations


If there is like the derivation of the formulas :D


The Attempt at a Solution



Actually this question is really in general and i would want to learn more about physics, its effect and the applications. Please help me :D tnx in advance guys
 
Physics news on Phys.org
if it isn't possible for you to take classes on this stuff and you don't have the ability to go out and buy yourself an introductory physics textbook, I would suggest going to khanacademy.org for a great, free online source of learning material related to physics, and a whole lot more
