PLEASE ANSWER: Students will identify that an electromagnet is controlled with an electrical charge from the battery. Students can take this in 2 different, yet correct directions. 1. They can determine that the battery is not functioning, therefore cannot power the motor, or that there is a malfunction within the motor causing the electromagnet to lose strength. If they do not mention either of these, then encourage them to look at the diagrams and think about what could cause the system to not function correctly.

Idon't know it i just need my points lol

When someone eats food

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.
