Analaysis Forces on Free Body Diagram

Click For Summary
SUMMARY

The discussion centers on analyzing forces in a Free Body Diagram (FBD) involving two blocks, m1 and m2, where m2 is positioned on top of m1. The scenario assumes no friction beneath m1 but friction between m1 and m2. Participants are asked to verify the correctness of the FBD and confirm whether both blocks experience the same acceleration. The consensus indicates that both blocks indeed share the same acceleration due to the frictional force acting between them.

PREREQUISITES
  • Understanding of Free Body Diagrams (FBD)
  • Basic principles of Newton's laws of motion
  • Knowledge of frictional forces and their effects on motion
  • Concept of acceleration in multi-body systems
NEXT STEPS
  • Study the principles of Newton's second law of motion in detail
  • Learn about friction coefficients and their impact on acceleration
  • Explore advanced Free Body Diagram techniques for complex systems
  • Investigate the effects of different friction scenarios on block motion
USEFUL FOR

Students and professionals in physics, engineering, and mechanics who are analyzing forces in multi-body systems and seeking to enhance their understanding of Free Body Diagrams.

So, I have created some blocks, and draw the FBD myself, am not sure if I did it right or not, so I'm going to upload these FBD here, and hope you guys can correct me if I'm wrong. Thanks a lot.
A block of m1 and m2, m2 is siting on top of m1. Assume there is no friction on the ground under m1, and there's friction between m1 and m2. Here are the FBD

Physics news on Phys.org
and this is the last one.
Do these two m1 and m2 have the same acceleration ? I think they do, but I'm not so sure...

Thanks
