Which of the following statements about this energy transformation is true? OA. Half of the kinetic energy is transformed into electric energy and heat energy.
OB. All of the kinetic energy is transformed into electric energy and heat energy.
OC. Half of the heat energy is transformed into electric energy.
OD. All of the heat energy is transformed into electric energy.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

Do you still need with this

If element x has 21 protons, element x has 21 electrons
