Worksheets are listed in the order I used them (and wrote them) and begin at the bottom of the page (Ch 16). Work, Energy, and Magnetism (Ch 5 + 10) - back to top. 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. Identify the type of energy contained in: A baseball that has just been thrown Kinetic A book hanging on the edge of a shelf Potential Light coming from a lightbulb Radiant. K, kalium 8. Work and energy reinforcement worksheet answers youtube. gold, Au 9. A group of ten friends, each of mass 50kg, want to test the strength of a trampoline. The temperature scale is marked on the tube.
2 K c. 37 C d. 147 K e. -42. If a player hits the ball at a level of off the ground, an angle of above the horizontal, and a velocity of, what is the total velocity of the ball as it passes over the center field wall at a height of? The centrifuge separates substances by density. Gold is an element, not a compound. Work and energy reinforcement worksheet answers key pdf. Plug in these zero values into the above equation. Each time the ball bounces, 10% of the kinetic energy is lost. 373 b. o c. 293 d. 310 e. -273 22. A pebble is dropped from a height of. Since it is starting from rest, it will not have any kinetic energy.
Colors will vary depending on the type of ink. The electrical energy in the battery is converted into kinetic energy by the clock's motor. A thermometer consists of a bulb filled with a liquid such as mercury or colored alcohol, connected to a sealed tube. 2-5 Apply, page 26 1. homogeneous mixture, or solution 2. A magnet could be used to separate them because iron is attracted to a magnet but aluminum is not. Conservation of Energy - AP Physics 1. Kinetic energy is the energy of motion. Elements cannot be broken into simpler substances by chemical changes.
None of the other answers. Chemical changes alter the identity of the substance, whereas physical changes do not. Thermodynamics (Ch 27) - back to top. The potential energy is converted to kinetic energy and sound energy. Chapter references are from the CPO IPC book. Glass is more brittle than plastic and requires different molding processes. Work and energy reinforcement worksheet answers printable. 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. This means that after colliding with the ground, the ball has 90% of its previous potential energy at the top of its flight.
First remove the paper clips with a magnet or your hand. No; they exert a force of. 'F Boiling - - 212' -- - - 100' - - - - - -373 --68' - - 32' ------- 0 ----- - -273 'C --20' K --310 Normal Body Temperature - 293 Room Temperature 5. What's important to realize is that because we are neglecting air resistance, we have a situation in which total mechanical energy is conserved. Print these out for your students on BRIGHTLY colored (to locate quickly). 2-3 Review and Reinforcement, pages 18-19 1. matter 2. solid, liquid 3. gas, plasma 4. chemical, physical 5. 6. a. Ca - Calcium a. 482 F, 250 C, 523 K 6. Students may suggest a wide variety of answers. For a baseball field, the distance between home plate and the center field wall is about and the wall is tall. At their highest jump, each friend is 2m above the trampoline.
Using conservation of energy, find out how much work gravity does on the ball when it travels from the bottom to the maximum height. 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. Chapters 22 - 25 - back to top. If you're seeing this message, it means we're having trouble loading external resources on our website. Don't have Adobe Acrobat Reader? Isolate the height variable and use the given values to solve for the maximum height. The limited expansion of the water could also result in difficulties in calibrating. Although you may never have thought about it, a washing machine acts as a centrifuge.
