Acceleration is not in direction of force

Click For Summary
SUMMARY

The discussion centers on the assertion that "acceleration is not in direction of force," particularly in the context of the equation dp/dt = mγ³[a + v × (v × a)]. This highlights scenarios where acceleration can deviate from the direction of the applied force. The conversation also touches on the implications of thread locking in forums, emphasizing the importance of maintaining coherent discussions. A participant acknowledges a misunderstanding regarding the relationship between acceleration and motion.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the concepts of force and acceleration
  • Knowledge of relativistic mechanics, particularly the Lorentz factor (γ)
  • Basic grasp of vector mathematics and cross products
NEXT STEPS
  • Study the implications of dp/dt in relativistic physics
  • Explore the relationship between force and acceleration in non-linear motion
  • Learn about the Lorentz force and its applications in electromagnetism
  • Investigate the role of thread moderation in online discussions and its impact on knowledge sharing
USEFUL FOR

Physics students, educators, and anyone interested in the nuances of force and acceleration in both classical and relativistic contexts.

"acceleration is not in direction of force"

The following quote was in a post now closed:
"i don't know how this person says that acceleration is not in direction of force
there fore angle HAS to be zero degrees."
If "force" is meant to be dp/dt, then "acceleration is not in direction of force."
Since dp/dt=m\gamma^3[a+vX(vXa)], there are important cases where
"acceleration is not in direction of force."

Meir, when a thread has been locked, it defeats the purpose of locking it, if a new thread starts off on attempting to dispute something that was said in the earlier thread. A continuation of the discussion is specifically what the moderating mentors wanted to avoid.
 
Err..Sorry it was me who typed that.I meant to say isn't acceleration in the direction of motion.Sorry my mistake
