As you have learned, an electromagnet is a magnet that is produced by electric current. Think about how electromagnets are used and what you have seen or heard of them being used for. In your initial discussion post, respond to the following: Which of the principles or laws discussed in this module explain how an electromagnet works? Describe in detail two modern applications of electromagnets.
Do these electromagnets draw a large amount of current or a little?
How do you know?
What supplies that current?
Why do you think electromagnets are used in these different ways?
What is the advantage of using an electromagnet rather than a permanent magnet?

Ibelieve the answer you're looking for is

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. 

Work is reduced while time is decreased
