A soccer ball is rolling towards the net. It bounces off a goal post towards Amy, who passes the ball to Betty. Betty holds
the ball under her foot. Below is a graph of the ball's position
over time

a) How far was Amy standing from the goal post? Answer to two significant
digits.

c) What is different about the ball's motion from 2 s to 4 s (from point B to
point C) compared to the motion from 4 s to 8 s (from point C to point D)?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
