PHYS 1A Lecture Notes - Lecture 2: Hypotenuse
Document Summary
A vector is usally denoted with an arrow over it. Vectors can be defined by a magnitude and an angle relative to the axis. Water is a dipole represented by a vector week 1 page 1 x=rcos y=rsin . Vector is always the hypotenuse. week 1 page 2 week 1 page 3. Two vectors are ewaual is they have the same magnitude and the same direction. A = b if a= b and they point along parallel lines. To derive the components of the new vector, add each component separately. When you have many vectors, just keep repeating the process until all are included. Continue with standard vector addition procedure. week 1 page 4. The only mulptiplication functions you can perfrom on a vector are. Result is a vector with same direction, different length. Distance: the length of the path you have followed (scalar)
