1. think about the modes of substances in the gas phase and explain why potential energy is included in the thermal energy of some substances in the gas phase, but not in other substances in the gas phase.
2. PE= E-bond + (1/2)E-thermal and KE = (1/2)Ethermal
when a monatomic solid/liquid turns into a gas, what are the PE and KE equal to then?
A box weighing 300N is shoved across the floor of an apartment by a force of 400 N exerted downward at an angle of 35.2° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.540, how long does it take to mov..

assume a charge starts at rest on an equipotential surface, is moved off that surface, and then is eventually returned to the same surface at rest after a round trip. How much work did it take to do this? Explain.
A woman is running at a constant velocity of 5 m/s in an attempt to catch a stopped bus 11m ahead of her. Though, it pulls away from her with a constant acceleration of 1 m/s2. How much time does it take her to reach the bus if she keeps running a..
