How does the macroscopic motion of a paper airplane affect the motion of the atoms that make up the piece of paper?
a. It has no significant effect.
b. The random movement of the atoms that make up the paper is replaced by orderly movement in the direction the airplane is moving.
c. The atoms all move in opposition to the direction the airplane is flying.
d. The atoms continue to move randomly but in addition each has an added velocity contribution in the direction the airplane is flying.
e. The motion in the opposite direction of the airplane no longer occurs.

Whether one object is warmer than another object has most to do with molecular
A) kinetic energy. B) potential energy. C) masses.
A 5.00-kg object moves clockwise around a 50.0 cm radius circular path. At one location, the speed of the object is 4.00 m/s
When the object next returns to this same location, the speed is 3.00 m/s. (a) How much work was done by non-conservative forces as the object moved once around the circle? (b) If the magnitude of the above non-conservative forces acting on the object is constant, what is the minimum value of this magnitude?
