Newton's third law is not correct

Click For Summary
SUMMARY

Newton's Third Law states that for every action, there is an equal and opposite reaction, focusing on the forces of interaction between two bodies. The incorrect statement among the options provided is D, which claims that the two forces are always equal in magnitude. The law does not require the forces to be of the same type (A) or to act on different bodies (B), as these conditions are not necessary for the law to hold true. Understanding these nuances is essential for accurately applying Newton's Third Law in physics.

PREREQUISITES
  • Understanding of Newtonian mechanics
  • Familiarity with force interactions
  • Basic knowledge of physics terminology
  • Ability to analyze statements logically
NEXT STEPS
  • Study the implications of Newton's Third Law in real-world applications
  • Explore examples of action-reaction pairs in various physical systems
  • Learn about the limitations of Newtonian mechanics in modern physics
  • Investigate the relationship between force and motion in classical mechanics
USEFUL FOR

Students of physics, educators teaching mechanics, and anyone interested in the foundational principles of classical physics will benefit from this discussion.

Newton's Third Law concerns the forces of interaction between two bodies.
Which of the following statements relating to the third law is not correct ?

A. The two forces must be of same type
B. The two forces must act on different bodies.
C. The two forces are always opposite in direction
D. The two forces are at all times equal in magnitude.
E. The two forces are equal and opposite so the bodies are in equilibrium

Ans is D but why can't be A or B ?

MUST THE FORCES are of same type?

Who said that the proper response is D?

Can you explain to us the third law in your own words?
