Acrylic and PVC are both types of plastic, but they’re different compounds. Acrylic has the chemical formula C5O2H8 meaning it is made of 5 carbon atoms, 2 oxygen atoms, and 8 hydrogen atoms. PVC has the chemical formula C2H3Cl. Compare the masses of the atoms that make up these plastics and come up with an explanation as to why PVC is more dense than acrylic

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.
