Physics — Easy Word Search
| Grid size | 12x10 |
|---|---|
| Words to find | 10 |

Ten essential physics words describing the basic forces and phenomena a first science class introduces.
The shortest words ("heat" and "mass") help new solvers gain confidence quickly, while longer entries such as "motion" and "gravity" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 10 words (force, energy, motion, speed, gravity, light, sound, heat, mass, power) across a 12x10 grid, using 14 of its 20 unique letters at least twice.
Why we chose this word list
"Mass" is used deliberately instead of "weight": they are related but scientifically different, and physics education should start with the correct term.
Both forces (force, gravity) and forms of energy (light, sound, heat) are represented, covering physics' two major early themes.
Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
Why this level is easy
- Only horizontal and vertical words — no diagonals
- No reversed words
- Short, everyday vocabulary
- No uncommon spellings
- Minimal overlaps between words
This puzzle satisfies every requirement of our easy level, as defined in our published methodology and applied consistently across every easy puzzle on this site.

Fifteen words distinguishing related concepts often confused with each other: velocity vs. speed, reflection vs. refraction.
The shortest words ("density" and "voltage") help new solvers gain confidence quickly, while longer entries such as "refraction" and "acceleration" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 15 words (velocity, acceleration, momentum, friction, pressure, density, wavelength, frequency, amplitude, voltage, magnetism, reflection, refraction, vibration, pendulum) across a 15x15 grid, using 18 of its 22 unique letters at least twice.
Why we chose this word list
"Velocity" is distinguished from the Easy list's "speed" on purpose: velocity includes direction, speed does not — a real, testable physics distinction.
"Reflection" and "refraction" are two genuinely different things light does, paired here so the contrast is reinforced rather than glossed over.
Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
Why this level is medium
- Horizontal, vertical and diagonal words
- No reversed words
- Mixed word lengths, some less common vocabulary
- Moderate overlaps between words
This puzzle satisfies every requirement of our medium level, as defined in our published methodology and applied consistently across every medium puzzle on this site.

Twenty terms from real advanced physics — quantum mechanics, relativity, thermodynamics — the vocabulary of a genuine university-level physics course.
The shortest words ("field" and "torque") help new solvers gain confidence quickly, while longer entries such as "electromagnetic" and "electromagnetism" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 20 words (thermodynamics, electromagnetism, quantum, relativity, mechanics, kinetic, potential, inertia, oscillation, resonance, torque, displacement, trajectory, conservation, radiation, subatomic, electromagnetic, gravitational, field, nuclear) across a 20x20 grid, using 19 of its 23 unique letters at least twice.
Why we chose this word list
"Kinetic" and "potential" energy are the two fundamental energy types every conservation-of-energy problem is built on — precise, foundational vocabulary.
"Quantum" and "relativity" represent the two major 20th-century physics revolutions — included together as the real dividing line between classical and modern physics.

Why this level is hard
- All eight directions, including reversed words
- Longer, denser word list
- Similar-looking decoy letter sequences in the filler
- Frequent overlaps between words
This puzzle satisfies every requirement of our hard level, as defined in our published methodology and applied consistently across every hard puzzle on this site.
