A horse whose mass is M gallops at constant speed v up a long hill whose vertical height is h, taking an amount of time t to reach the top. The horse's hooves do not slip on the rocky ground, so the work done by the force of the ground on the hooves is zero (no displacement of the force). When the horse started running, its temperature rose quickly to a point at which from then on, heat transferred from the horse to the air keeps the horse's temperature constant.(b) Next consider the Universe as the system of interest. Write out the Energy Principle for this system. Remember that terms on the left hand side should include all energy changes for the system, while the terms on the right hand side shold relate to the surroundings. Which of the following terms are equal to 0?4
?Ugrav
?Echemical
?K
Q
?(mc2)
?Ethermal, air
?Ethermal, horse
W

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
