Question: Answer the following question given this paragraph: with a minus sign because the displacement while stopping and the force from floor are in opposite directions (cos = cos 180 = 1) . The floor removes energy from the system, so it does negative work. The kinetic energy the person has upon reaching the floor is the amount of potential energy lost by falling through height. Q: When someone falls, the kinetic energy the person has upon reaching the floor is the amount of what energy lost by falling through height? Choices: - gravitational energy - thermal energy - nuclear energy - potential energy A:
Answer: potential energy

Question: Answer the following question given this paragraph: A: The modern kinetic theory of matter is remarkably similar to Democritus' ideas about the motion of atoms. According to this theory, atoms of matter are in constant random motion. This motion is greater in gases than in liquids, and it is greater in liquids than in solids. But even in solids, atoms are constantly vibrating in place. Q: What theory says atoms of matter are in constant random motion? Choices: - the theory of relativity - modern residual theory - sound kinetic theory - modern kinetic theory A:
Answer:
modern kinetic theory
