Newton’s First Law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Why do we see lightning before hearing thunder?
Light travels faster than sound, so we see the lightning first, even though both happen at the same time.

What is the speed of light in vacuum?
The speed of light in vacuum is approximately 3,00,000 km per second.

Why do objects appear to float in space?
In space, there is no significant gravitational force, so objects appear to float due to weightlessness.

What is the principle of a simple electric motor?
A simple electric motor works on the principle that a current-carrying coil in a magnetic field experiences a force that causes rotation.

How is sound produced and how does it travel?
Sound is produced by vibrations and travels through a medium like air, water, or solids as sound waves.

Why does a pencil look bent when placed in water?
This happens due to refraction, where light bends as it moves from water to air, making the pencil appear bent.

What is the difference between concave and convex mirrors?
A concave mirror curves inward and can form real or virtual images, while a convex mirror curves outward and always forms a virtual, smaller image.

Why do we wear dark clothes in winter and light clothes in summer?
Dark colors absorb more heat, keeping us warm, while light colors reflect heat, keeping us cool.

How does a rainbow form?
A rainbow forms when sunlight passes through raindrops, bending and splitting into different colors due to refraction and reflection.

Chemistry Questions and Answers

What is the chemical formula of water?
The chemical formula of water is H₂O.

Why does salt dissolve in water?
Salt dissolves in water because water molecules break the bonds between the salt particles and surround them.

What is rusting and how can it be prevented?
Rusting is the formation of iron oxide when iron reacts with oxygen and water. It can be prevented by painting, galvanization, or oiling.

What is an acid and a base?
An acid is a substance that releases hydrogen ions (H⁺) in a solution, while a base releases hydroxide ions (OH⁻).

Why does lemon taste sour?
Lemon tastes sour because it contains citric acid, which is an organic acid.

What is the difference between a physical change and a chemical change?
A physical change does not form a new substance, while a chemical change results in the formation of a new substance with different properties.

Why do some metals react with acid to produce gas?
Metals react with acids to form hydrogen gas and a salt due to a chemical reaction.

What happens when baking soda is mixed with vinegar?
Baking soda reacts with vinegar to produce carbon dioxide gas, causing fizzing and bubbles.

What is an alloy? Give an example.
An alloy is a mixture of two or more metals to enhance properties. An example is steel, which is a mixture of iron and carbon.

Why do we store pickles in glass or plastic containers?
Pickles contain acids that can react with metals, so they are stored in non-reactive containers like glass or plastic.

Biology Questions and Answers

Proteins help in growth, repair of tissues, and building muscles.

What is the role of the brain in the body?
The brain controls all body functions, thoughts, memory, and coordination.

Why do leaves appear green?
Leaves appear green because they contain chlorophyll, which absorbs light for photosynthesis.

General Science Questions and Answers

Why does ice float on water?
Ice floats on water because it is less dense than liquid water.

How does a thermometer work?
A thermometer measures temperature by the expansion and contraction of liquid inside it, such as mercury or alcohol.

What is the role of vitamins in our body?
Vitamins help in various body functions like immunity, vision, and energy production.

Why do we see stars twinkling?
Stars appear to twinkle due to the refraction of light as it passes through different layers of Earth’s atmosphere.

What is an ecosystem?
An ecosystem is a system where living organisms interact with each other and their environment.

How do magnets work?
Magnets work by producing a magnetic field that attracts or repels certain metals like iron and nickel.

Why do we need calcium for our body?
Calcium is essential for strong bones and teeth, and also helps in muscle function.

What happens when sugar is dissolved in water?
When sugar dissolves, its molecules spread throughout the water, making a solution.

Why do astronauts wear space suits?
Astronauts wear space suits to provide oxygen, protect against radiation, and maintain body pressure in space.
