PHYS 1 Lecture Notes - Lecture 3: Cross Product
Document Summary
Use right hand rule to find the direction of the resultant vector from the cross product. The resultant vector is perpendicular to both of the original vectors. Unlike dot (scalar) product, vector product cannot be negative. If given and in their component form ( Will not be used in this course. Quantities: kinematics = the study of motion. Position vector: arrow that points from origin to a point in space. Displacement vector: arrow from initial position to final position. Changing direction = changing velocity (and thus acceleration) since is a vector quantity. If speed is constant, acceleration is not necessarily 0 (instantaneous) acceleration: same except shrink thee time interval to infinitesimal.
