proportional to its charge, or F = qE If the charge is not fixed in space, it will accelerate according to Newton's Second Law F = ma Therefore the acceleration of a charged mass is This lab will let you explore these ideas using simulation software. OBJECTIVE To apply and further develop your knowledge of electric charges, forces, fields, and field lines through the simulation of a moving charge in a field of other particles as well as physical barriers.
