Study the position-time graph for a bicycle.
which statement is supported by the graph?
position vs time
the bicycle has speed but not velocity
the bicycle is moving at a constant velocity
the bicycle has a displacement of 3 m.
the bicycle is not in motion.
position (m)
2 3
time (s)
save and exit

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                                         : )

0.19 m/s and 0.45 m/s

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
