Describing motion is done using both words and graphs. The wording can be confusing but the graphs always give you a picture of what is happening. Remember that motion is a change in position measured by distance and time. Making a graph showing distance and time can tell you a great deal about the motion of an object. Look at the axes below. Time is always plotted along the X-axis and Distance is always plotted along the Y-axis. Time is usually in seconds but can also be in minutes or hours. Distance is usually in meters but can be in feet or inches. Questions: 1. How many seconds are recorded on the graph? 2. How many feet are recorded on the graph? 3. What distance was traveled after 2 seconds? 4. How long did it take the object to travel 9 feet?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

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
