Step-by-step solution for: Work Energy and Power Answer Key | PDF | Potential Energy | Force
To solve this crossword puzzle, we need to match the definitions in the "Across" and "Down" sections with the correct physics terms related to energy and power. Let's go through each clue one by one.
Step 1: Solve the Across Clues
* 2. State of energy involved in weighing, flow or a spring energy.
* Energy associated with motion (flow) or position/state (spring/weighing context usually implies potential, but "flow" suggests kinetic). However, looking at common terms, "Kinetic" is energy of motion. Let's look at other clues. Actually, "State of energy... spring energy" often refers to Potential energy (stored in a spring). But let's check the letter count later. Let's look at clue 15 first.
* Let's re-read carefully: "State of energy involved in weighing [position], flow [motion] or a spring energy." This is a bit ambiguous. Let's look at the grid length if possible, or cross-references. Let's hold on this.
* *Correction*: Often, "energy of motion" is Kinetic. "Stored energy" is Potential. Let's look at clue 15: "Work done in a certain amount of time." That is definitely Power.
* Let's look at clue 3: "A stored energy such as mechanical or compressed spring..." This is clearly Potential.
* So, if 3 is Potential, what is 2? "State of energy involved in weighing, flow or a spring energy." Wait, maybe it's Mechanical? Mechanical energy is the sum of kinetic and potential. Or maybe Kinetic? Let's look at the letters.
* Let's skip to easier ones to get crossing letters.
* 4. The mass of the object’s...
* This seems incomplete. Usually, "The mass of the object's [something]". Let's look at the grid or context. Maybe it's Matter? No. Let's look at Down clues.
* 6. ...created use electricity, but only when there are forces into...
* This text is garbled. Let's look for standard definitions.
* Let's look at 15. Work done in a certain amount of time.
* Definition: Power = Work / Time.
* Answer: POWER (5 letters).
* 17. Stored energy
* Answer: POTENTIAL (9 letters) or just STORED? Usually "Potential Energy". Let's assume POTENTIAL.
* 18. A scalar quantity which is an example of a...
* Energy is a scalar quantity. Work is also a scalar.
* Let's look at 20. The ability to do work.
* Answer: ENERGY (6 letters).
* 21. It moves towards...
* Vague. Let's look at 23. When heat does not an object is equal to the change in kinetic and potential energy.
* This sounds like the Work-Energy Theorem or Conservation of Energy. If heat is ignored, Work = Change in Mechanical Energy.
* Maybe the answer is WORK?
Let's try to interpret the garbled text by looking for standard physics vocabulary words that fit typical crossword lengths.
Re-evaluating based on standard Physics Terms:
Across:
* 2. "State of energy involved in weighing, flow or a spring energy." -> This might be MECHANICAL. Mechanical energy involves motion (flow/kinetic) and position (weighing/potential).
* 3. "A stored energy such as mechanical or compressed spring..." -> POTENTIAL.
* 4. "The mass of the object’s..." -> Likely MASS or related to inertia? Let's wait.
* 6. "...created use electricity..." -> Maybe ELECTRICAL?
* 15. "Work done in a certain amount of time." -> POWER.
* 17. "Stored energy" -> POTENTIAL is already used in 3? Or maybe 3 is ELASTIC? "Compressed spring" is Elastic Potential Energy. If 3 is ELASTIC, then 17 could be POTENTIAL.
* 18. "A scalar quantity which is an example of a..." -> WORK or ENERGY.
* 20. "The ability to do work." -> ENERGY.
* 21. "It moves towards..." -> MOTION?
* 23. "When heat does not an object is equal to the change in kinetic and potential energy." -> This describes WORK (Work-Energy principle).
Down:
* 1. "Friction and air resistance is an example of what type of force?" -> NONCONSERVATIVE or DISSIPATIVE? Or simply FRICTION? The clue asks for the type of force. Friction is a CONTACT force? Or RESISTIVE? Let's look at standard worksheets. Often, friction is cited as a NON-CONSERVATIVE force.
* 5. "Energy of running water?" -> HYDRO or HYDRAULIC? Or KINETIC? Running water has kinetic energy. But specifically, hydroelectric power uses water. Let's guess HYDRO.
* 7. "Energy of moving objects?" -> KINETIC.
* 8. "Unit of potential energy and kinetic energy?" -> JOULE.
* 9. "An object gains energy when the gravitational force is added..." -> HEIGHT? Or LIFTED?
* 10. "Unit of work" -> JOULE.
* 11. "Rate at which power used is one joule of energy transferred in one second?" -> WATT.
* 12. "The product of force exerted on an object times the distance the object moves in the direction of the force" -> WORK.
* 13. (Missing text in crop, but likely related to energy types).
* 14. (Missing text).
* 16. (Missing text).
* 19. (Missing text).
* 22. (Missing text).
Let's refine the answers based on the visible text and common physics crosswords.
Across Solutions:
* 15: Work / Time = POWER
* 20: Ability to do work = ENERGY
* 17: Stored energy = POTENTIAL
* 3: Stored energy (spring) = ELASTIC (fits "compressed spring")
* 2: "State of energy... flow... spring". If 3 is Elastic and 17 is Potential, 2 might be MECHANICAL (sum of kinetic and potential).
* 18: Scalar quantity... example of WORK (Work is a scalar).
* 23: "When heat does not... equal to change in kinetic and potential". This is the definition of WORK done by non-conservative forces being zero, so Work_ext = Delta E_mech. The answer is likely WORK.
* 6: "Created use electricity". Likely ELECTRICAL.
* 4: "The mass of the object's...". Could be INERTIA? Or WEIGHT? Weight is force. Mass is measure of inertia. Let's assume MASS isn't the answer because it's in the clue. Maybe MATTER?
* 21: "It moves towards". MOTION?
Down Solutions:
* 1: Friction/Air resistance type of force. NONCONSERVATIVE is long. DISSIPATIVE? RESISTIVE? Let's check letter counts if I could see the grid. Without grid, FRICTION itself is a force, but the clue says "Friction... is an example of what type". A common answer is CONTACT or NON-CONSERVATIVE. Given the space, maybe DRAG? No. Let's stick with NONCONSERVATIVE if it fits, or RESISTIVE.
* 5: Energy of running water. HYDRO energy? Or KINETIC? "Running water" specifically hints at HYDRO.
* 7: Energy of moving objects. KINETIC.
* 8: Unit of PE and KE. JOULE.
* 10: Unit of work. JOULE.
* 11: Rate... one joule per second. WATT.
* 12: Force x Distance. WORK.
* 9: Object gains energy when gravitational force is added... HEIGHT? When you lift something (add height), it gains PE.
Let's assemble the most likely standard answers for this specific worksheet "Energy and Power".
Across:
2. MECHANICAL (Energy involving motion and position/springs)
3. ELASTIC (Specifically for springs)
4. INERTIA (Mass is a measure of inertia? Or maybe WEIGHT?) -> Let's look at clue 4 again: "The mass of the object's...". It cuts off. It might be "The mass of the object's matter"? Unlikely. Let's assume it crosses with other words.
6. ELECTRICAL
15. POWER
17. POTENTIAL
18. WORK (Scalar quantity)
20. ENERGY
21. MOTION (Or FORCE?)
23. WORK
Down:
1. NONCONSERVATIVE (Friction is a non-conservative force)
5. HYDRO (or HYDRAULIC)
7. KINETIC
8. JOULE
9. LIFTED (Object gains PE when lifted)
10. JOULE
11. WATT
12. WORK
Let's double check Clue 2: "State of energy involved in weighing, flow or a spring energy."
"Weighing" relates to gravity (Potential). "Flow" relates to motion (Kinetic). "Spring" relates to Elastic. The combination is MECHANICAL Energy.
Clue 3: "A stored energy such as mechanical or compressed spring..."
Actually, the text says "such as mechanical OR compressed spring". This phrasing is weird. Usually, it's "Such as gravitational or elastic". If it says "mechanical", it might be a typo for "gravitational". But "compressed spring" is definitely ELASTIC.
Clue 17: "Stored energy". General term is POTENTIAL.
Clue 18: "A scalar quantity which is an example of a..."
Energy and Work are scalars. Since 20 is Energy, 18 is likely WORK.
Clue 23: "When heat does not an object is equal to the change in kinetic and potential energy."
This refers to the principle where Work done = Change in Mechanical Energy (if no heat loss). So the answer is WORK.
Clue 1: "Friction and air resistance is an example of what type of force?"
In physics contexts regarding energy, these are NONCONSERVATIVE forces. They remove mechanical energy from the system.
Clue 5: "Energy of running water?"
Often called HYDRO energy in simple contexts, or KINETIC if strictly physics. But since 7 is Kinetic, 5 is likely HYDRO.
Clue 9: "An object gains energy when the gravitational force is added..."
This is poorly phrased. It probably means "An object gains potential energy when its HEIGHT is increased." Or when it is LIFTED. Given "gravitational force is added" might mean working against gravity. Let's guess HEIGHT or LIFTED.
Clue 4: "The mass of the object's..."
Could be INERTIA. Mass is the measure of inertia.
Let's provide the final list based on these deductions.
Final Check of Answers:
Across:
2. MECHANICAL
3. ELASTIC
4. INERTIA (Best guess for "mass of the object's...")
6. ELECTRICAL

7. KINETIC
8. JOULE
9. HEIGHT (or LIFTED)
10. JOULE
11. WATT
12. WORK
Note: Some clues are cut off or garbled, so these are the most scientifically accurate terms fitting the definitions provided.
