The dot product is a type of vector multiplication. The dot product of two vectors is defined by the relation θ cos B A B A = If the vectors are expressed in terms of their components, an equivalent way of calculating the dot product is z z y y x x B A B A B A B A + + =

k-work, dK, measures the kinetic energy transfer to a particle by some interaction. It is defined by the relation r d F p d v dK = = Note that dK, like K, is a scalar and is measured in the same units as kinetic energy.
During a tiny time interval dt , an object whose velocity is experiences an interaction that delivers a momentum transfer

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
