33 words
- circuit परिपथ
- A complete loop that electricity flows around, from the cell through the bulb and back.
- PhysicsTechnology
- condensation सघनन
- When a gas cools and turns back into a liquid, like drops on a cold glass.
- ChemistryEnvironmentPhysics

- PhysicsChemistry
- energy ऊर्जा
- What is needed to make things move, heat up, light up or grow.
- PhysicsTechnologyEnvironmentBiology
- evaporation वाष्पीकरण
- When a liquid slowly turns into a gas (vapour), like puddles drying in the sun.
- ChemistryEnvironmentPhysics
- evidence प्रमाण
- What you saw or measured that shows whether an idea is right.
- PhysicsChemistryBiologyEnvironmentTechnology
- fair test निष्पक्ष परीक्षण
- A test where you change only one thing, so you know what caused the result.
- PhysicsChemistryBiologyEnvironmentTechnology
- force बल
- A push or a pull. Forces can start, stop or turn things.
- PhysicsTechnology
- friction घर्षण
- A force that slows things down when two surfaces rub together.
- PhysicsTechnology
- fulcrum आधार बिन्दु
- The fixed point a lever turns on.
- PhysicsTechnology
- gravity गुरुत्वाकर्षण
- The pull that makes things fall towards the Earth.
- Physics
- insulator कुचालक
- A material that does not let electricity or heat pass through easily, like plastic.
- PhysicsTechnology
- lever उत्तोलक
- A bar that turns on a fixed point to lift heavy loads with less effort, like a see-saw.
- PhysicsTechnology
- magnet चुम्बक
- An object that pulls iron and steel towards it.
- Physics
- mass पिण्ड
- How much matter something has, measured in grams or kilograms. It is the same everywhere.
- PhysicsChemistry
- opaque अपारदर्शी
- Lets no light through, like wood or a book.
- Physics
- particle कण
- A tiny piece that matter is made of, far too small to see.
- ChemistryPhysics
- pole ध्रुव
- One of the two ends of a magnet (north and south), where its pull is strongest.
- Physics
- prediction अनुमान
- What you think will happen before you try it. It is fine if it turns out wrong.
- PhysicsChemistryBiologyEnvironmentTechnology
- pressure चाप
- How much force presses on an area. A sharp knife has high pressure at its edge.
- Physics
- reflection परावर्तन
- When light bounces off a surface, like a mirror.
- Physics
- refraction अपवर्तन
- When light bends as it passes from one material into another, like from air into water.
- Physics
- resistance प्रतिरोध
- How much something slows down the flow of electricity, measured in ohms (Ω).
- PhysicsTechnology
- shadow छाया
- A dark shape made where an object blocks the light.
- Physics
- speed गति
- How far something travels in a certain time, like kilometres per hour.
- PhysicsMathematics
- temperature तापक्रम
- How hot or cold something is, measured in degrees Celsius (°C).
- ChemistryPhysicsEnvironment
- transparent पारदर्शी
- Lets almost all light through, so you can see clearly through it, like glass.
- Physics
- variable चर
- Something that can change in an experiment. Change one, measure another, and keep the rest the same.
- PhysicsChemistryBiologyEnvironmentTechnology
- voltage भोल्टेज
- The push that makes electricity flow, measured in volts (V).
- PhysicsTechnology
- volume आयतन
- How much space something takes up, measured in millilitres or cubic centimetres.
- PhysicsChemistryMathematics
- weight तौल
- The pull of gravity on something, measured in newtons. It is less on the Moon.
