Newtons third law question- Action reaction pair

Click For Summary
SUMMARY

The discussion centers on Newton's Third Law of Motion, specifically regarding the interaction between a 2000kg car and a 1000kg garbage can. The car exerts a force (CB) on the garbage can, while the garbage can exerts an equal and opposite force (BC) on the car. According to the law, the magnitudes of these forces are equal, confirming the principle that for every action, there is an equal and opposite reaction.

PREREQUISITES
  • Understanding of Newton's Laws of Motion
  • Basic knowledge of force diagrams (Free Body Diagrams)
  • Familiarity with concepts of mass and acceleration
  • Ability to analyze force interactions in physical systems
NEXT STEPS
  • Study detailed applications of Newton's Third Law in various physical scenarios
  • Explore the implications of force interactions in engineering contexts
  • Learn how to construct and analyze Free Body Diagrams effectively
  • Investigate real-world examples of action-reaction pairs in motion
USEFUL FOR

Students studying physics, educators teaching Newton's laws, and anyone interested in understanding fundamental principles of motion and force interactions.

Homework Statement



A 2000kg car pushes a 1000kg garbage can at constant speed . The car exerts a force of magnitude CB on the garbage can, and the garbage can exerts a force BC on the car. Which force has greater magnitude, or are they equal? explain

Homework Equations


Fcb=-Fbc


The Attempt at a Solution



Esentially, I drew 2 FBD's and showed one for the car with a force on the right CB ... the second FBD of the garbage can has a force pointing to the left of BC... which is equal and opposite magnitude of CB

Basically i just explained Newtons third law

Is this correct?

That is right, and it is just Newton's third law, indeed.
