SUMMARY

The symbols i^ and j^ represent unit vectors in the x and y directions, respectively, in vector notation. In the context of the discussion, the vector 6i + 8j is equivalent to the Cartesian coordinates (6, 8). Understanding these unit vectors is crucial for calculating work done by a force along different paths, such as ABD, ACD, and AD, using the dot product method. This foundational knowledge simplifies the process of solving physics problems involving vectors.

PREREQUISITES
  • Understanding of vector notation and Cartesian coordinates
  • Familiarity with unit vectors in physics
  • Basic knowledge of the dot product operation
  • Concept of work done by a force in physics
NEXT STEPS
  • Study vector addition and subtraction in physics
  • Learn about the dot product and its applications in calculating work
  • Explore the concept of force vectors and their representation
  • Investigate different paths and their impact on work done in physics
USEFUL FOR

Students studying physics, educators teaching vector concepts, and anyone interested in understanding the application of vectors in work and force calculations.

[SOLVED] Quick question..

What does the i^ and the j^ symbol mean?
A particle moves from A to D in the figure while experiencing force http://img249.imageshack.us/img249/4294/renderet0.gif . View Figure How much work does the force do if the particle follows path (a) ABD,(b) ACD, and (c) AD?

I just want to know that before i start the question.

In this sense, i and j refer to the unit vectors in the x and y directions, respectively. So, the vector 6i+8j is identical to the vector (6,8) using "normal" notation.
 
thanks a lot! The question was a breeze after you explained that. Just had to find the dot product to find the work done.
