Static & kinetic friction could cause motion?

Click For Summary
SUMMARY

This discussion centers on the concepts of static and kinetic friction and their roles in causing motion. A participant seeks examples of each type of friction that can lead to motion, noting that friction typically opposes motion. The response provided highlights that static friction can enable a plane to lift off the ground, illustrating how friction can facilitate motion under certain conditions.

PREREQUISITES
  • Understanding of basic physics concepts, specifically Newton's laws of motion.
  • Familiarity with the definitions of static and kinetic friction.
  • Knowledge of how friction interacts with forces in motion.
  • Basic grasp of real-world applications of friction, such as in aviation.
NEXT STEPS
  • Research the principles of static friction and its role in initiating motion.
  • Explore kinetic friction and its effects on moving objects.
  • Study real-world applications of friction in engineering, particularly in aviation.
  • Learn about the coefficient of friction and how it varies between different materials.
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the practical implications of friction in motion, particularly in contexts like aviation and mechanical engineering.

Static & kinetic friction could cause motion??

Homework Statement



I have a question about friction. I was asked to discuss an example where static friction and kinetic friction could cause motion. One example for each. I have never learned friction causing motion and I thought of it but could not come up with anything that makes sense. I'll appreciate any examples you guys can think of. All I know is friction opposes motion.
Thanks

A plane would be one example. The friction can make the plane lift off the ground.

Cheers
