Across
- 1. I’m the time it takes for half to decay, A measure in physics that won’t sway. Used in dating ancient remains, What am I, with my constant gains? (4,4)
- 4. I'm the rate of work, the pace of flow, In watts or horsepower, my values show. From generators to engines, I'm the call, What am I, that drives them all? (5)
- 7. In circuits I act against the flow, Electrons struggle, and heat will show. Ohm's law defines me, as you might know, What am I, where currents slow? (10)
- 11. I bend the path of light or sound, In glass and water I am found. My index shows how fast they go, What am I, causing the wave to slow? (10)
- 12. I flow in circuits, through wires I race, Electrons moving at a rapid pace. Coulomb is my unit, as you might surmise, What am I, in electric guise? (6)
- 16. I’m the reason why helium can soar, While lead sinks low, heavy and more. Mass per unit volume, I'm the key, What am I, in physics' decree? (7)
- 17. I resist the change, whether fast or slow, Newton's First declares it's so. Objects at rest or in motion's flow, What am I, that keeps this status quo? (7)
- 18. When you lift a box or climb a hill, I measure the effort, the strength, the will. Force times distance is my name, In joules or calories, I'm always the same. (4,4)
- 20. I am the push or pull, strong or weak, Behind every motion, I'm what you seek. Newton described me in his famous laws, What am I, the hidden cause? (5)
Down
- 2. I’m the wave's height from peak to the middle, Energy measured, so answer my riddle. The taller I am, the stronger the wave, What am I, that surfers crave? (9)
- 3. I am the measure of matter's span, Inertia depends on me, understand? Kilograms or grams, will quantify, on a balance, and that's no lie (4)
- 5. I'm the energy of motion, dynamic and fleet, When objects move, I'm what they greet. From speeding cars to winds that blow, What am I, in motion's flow? (7)
- 6. I'm the displacement divided by time, With units like meters per second to rhyme. Speed is my partner, yet different we are, What am I, moving near and far? (8)
- 8. At rest or in motion, I'm force's kin, a potential to move is where I begin. Once in motion, kinetic I become, What am I, in physics' hum? (6)
- 9. I curve space-time and make you fall, Holding planets, big and small. Newton then Einstein told my tale, What am I, where masses prevail? (7)
- 10. When objects collide and then they split, I measure how they transfer hit. Mass and velocity are my friends, In closed systems, my total never ends. (8)
- 13. How do we measure velocity's climb? For changes in motion, I'm the prime. Meters per second squared, I portray, What am I, in swift display? (12)
- 14. I'm the charge's flow, the lively parade, Through wires and circuits, I'm relayed. Ampere is my unit, the electric flow, What am I then, surely you know? (7)
- 15. I’m the time it takes for one complete round, A cycle in motion, in waves I’m found. From crest to crest or trough to trough, What am I, is that so tough? (6)
- 19. I'm the measure of effectiveness, the task's true score, In percentage or decimal, I show what's more. Useful Output by input, I calculate, If you want to save money then I am your mate (10)
