aluminum has a specific heat of 0.902 j/g x oc. two pieces of aluminum, with masses of 10 kg, cool from 400 oc to 100oc. one mass is round; the other is a cube. all but one statement is true regarding the energy transformation. that is
a) both masses lose the same amount of heat energy.
b) the masses cool in approximately the same amount of time.
c) the heat energy lost is directly related to the shape of the object.
d) the kinetic energies of the masses decrease during the cooling process.

Independent variable is something that is changed in a experiment.

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.
