Therefore, we get: Substituting in the expression for potential energy, we get: Note that this problem cannot be solved by using the force of gravity and force of friction because we do not know the angle of the slope. A magnet could be used to separate them because iron is attracted to a magnet but aluminum is not. Elements cannot be broken into simpler substances by chemical changes. They all land on the trampoline at the same time and decelerate at a constant rate to a point of zero velocity over a period of 0. These worksheets are self-explanatory. Terry believes he can throw a ball vertically and hit a target above himself.
Disregard the effects of air resistance. Mr. Murray's worksheets incorporate notes with in-class practice and review. Keeping this in mind, we can equate the total mechanical energy of the block at any point during its fall with its initial potential energy, which we calculated above. Kinetic energy is the energy of motion. When the ball reaches maximum height, its velocity is zero (zero kinetic energy). The loop is 15 meters tall. Neglect air resistance and the distance the trampoline sags as a result of the friends landing. Furthermore, we can remove final potential energy if we say that the final height is 0m. 2 K c. 37 C d. 147 K e. -42. If the ball weighs, how fast must it be traveling when it leaves his hand to just reach the target? Removing chlorophyll pigment from leaves might be done by chromatography.

The symbol for gold is Au. The electricity stored in the battery is potential energy. First remove the paper clips with a magnet or your hand. The water boils off, leaving the solids behind. Method 1: Conservation of Energy.
Make sure that their answers reveal the understanding that physical changes do not alter the identity of a substance and that chemical changes, such as burning, digesting, and rusting, do involve the formation of a new substance. Crude oil is broken down by heat, vaporized and allowed to condense into various liquids. The burner provides the heat needed to vaporize the liquids. Students that actually read the front of the worksheets are able to complete the back of the worksheet and the homework. If we neglect air resistance, what is the block's total energy at a height of 4m from the ground? Separating sand from water can be done by filtration. Don't have Adobe Acrobat Reader? H. e added 173 to the Celsius temperature instead of 273. Work and energy reinforcement worksheet answers sheets. Once the block is released from its resting position, it will begin to fall towards the ground. The separation technique that takes advantage of different boiling points is called distillation.
The system just converts energy into different forms. The sugar in sugar water can be removed by crystallization. Then filter the sand from the water.

Choosing the bottom of the incline to be the zero height, the ball starts out with kinetic energy and zero potential energy. Work, Energy, and Magnetism (Ch 5 + 10) - back to top.
Elements and compounds are called pure substances because they have a unique set of chemical and physical properties. Sunlight is an example of radiant energy. Each time the ball bounces, 10% of the kinetic energy is lost. A rubber ball is released from a height of and is allowed to bounce repeatedly. Therefore we can say: We can find the final y-componenet using our conservation of energy equation: Substituting in our expressions: Canceling out mass and rearranging for final velocity: Note that this is one of the big five kineamtics equations with which you should be familiar. Rather, all of its energy will be in the form of gravitational potential energy. If new properties appear that suggest a new chemical substance is present, matter has undergone a chemical change. Note: The only reason we can use this method is because we know the height at which the ball crosses over the center field wall. 2-3 Review and Reinforcement, pages 18-19 1. matter 2. solid, liquid 3. gas, plasma 4. chemical, physical 5. Potential energy is expressed as: Kinetic energy is expressed as: Energy must be conserved, so set up the following equation: The initial height can be treated as zero, as can the final velocity. Thus, not all mixtures are solutions.
Energy in a system must be conserved, and the energy in the falling pebble is either potential or kinetic: Potential energy is represented by the terms. Colors will vary depending on the type of ink. The correct answer is 373 K. The boiling point of water in Fahrenheit is 212 F. She should heat the candy to 224 F. Absolute zero is measured on the Kelvin scale. 2-5 Apply, page 26 1. homogeneous mixture, or solution 2.
D. Cough syrup – homo? Sugar – compound (pure) b. Fluorine - F c. W - Tungsten d. Iron - Fe e. Al - Aluminum f. Sodium - Na 6. No, because compounds contain two or more elements combined in a fixed proportion. The limited expansion of the water could also result in difficulties in calibrating. More information is needed to solve. 2-5 Review and Reinforcement, pages 28-29 1. heterogeneous 2. pure 3. heterogeneous 4. pure 5. homogeneous 6. heterogeneous 7. homogeneous 8. heterogeneous 9. homogeneous 10. pure 11. filtration 12. filtration 13. crystallization 14. distillation 15. chromatography 16. electrolysis 17. distillation 18. The electrical energy in the battery is converted into kinetic energy by the clock's motor. Physics Reviews for Final Exam - back to top. Included here are four foldable mini books (and identical reading passages) that cover motion, acceleration, speed, work, potential & kinetic energy, types of energy, newton's laws of motion, and types of forces - gravity, friction, etc. The chemical energy in the battery is converted to electrical energy, which is changed to mechanical energy in the running of the motor. Before mixing, the two liquids filled each graduated cylinder completely.
A pebble is dropped from a height of. For example, the water, carbon dioxide, and nutrients absorbed by the plant are chemically rearranged to form the living material of the plant cells. 2-5 Explore, page 25 1. No, the sample must boil to be separated. Finally, the mechanical energy of the motor is converted to heat energy as the sandpaper rubs against the piece of metal.. 2-1 Practice Problems, page 6 *1.
Although chemical properties describe how elements chemically react with each other, in the case of inert elements, a descriptive property would be "non-reactive. "
