Kinetic and potential energy calculations key
WebFrom these, it’s easy to see that kinetic energy is a scalar since it involves the square of the velocity (dot product of the velocity vector with itself; a dot product is always a scalar!). Also, momentum is clearly a vector since it involves the velocity vector. Since one is a vector and the other is a scalar, this means that kinetic energy and momentum will both be … http://www.queenwhitley.com/files/documents/pe_and_ke_practice_problems.pdf
