Where on the position graph is the velocity positive?
C
D
Remember, velocity = slope of the position graph.
A. from D to F
B. from A to C and from E to F
C. from A to B
D. only from E to F

the body's situation won't change the forces are equal opposit and on the same body

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
