1. Alex is at the Cafe (not the "Real cafe"), when he discovers that he has a paper cut. After getting a band aid from the Health Center, he travels to the library to meet up with his friend.
a. What is Alex's distance?
b. What is Alex's displacement?

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                                         : )
