Suppose you plug in two different devices into outlets (home outlets are all 120V). One is a hairdryer that uses 10 Amps, and the other is a lightbulb that uses 1Amp of current. What does
that tell you about the resistance of each device?
explain?

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

You would need to take a picture so i can see

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. 

F  you double the  force, you double the acceleration, but  if  you double the  mass, you velocity. all bodies accelerate at the  same  rate regardless of size or  mass.
