ASI Police Test Everyday Science and Computer flashcards — 50 questions with answers

What is the formula for force in terms of mass and acceleration?
Force = mass × acceleration (F = ma); SI unit is the newton (N).
State Newton's First Law of Motion.
A body remains at rest or in uniform motion in a straight line unless acted upon by an external force (law of inertia).
What is the difference between speed and velocity?
Speed is the distance covered per unit time (scalar). Velocity is displacement per unit time in a given direction (vector).
What is the formula for work done, and its SI unit?
Work = Force × Distance (W = F × d); SI unit is the joule (J).
Define kinetic energy and give its formula.
Kinetic energy is the energy of a moving body: KE = ½mv², where m is mass and v is velocity.
What is potential energy and its formula due to height?
Stored energy due to position; gravitational PE = mgh (mass × gravitational acceleration × height).
State the law of conservation of energy.
Energy can neither be created nor destroyed, only transformed from one form to another; total energy remains constant.
What is the value of gravitational acceleration (g) on Earth?
Approximately 9.8 m/s² (often rounded to 10 m/s²).
What is the SI unit of power and its formula?
The watt (W); Power = Work / Time = Energy / Time.
What is the approximate speed of light in a vacuum?
About 3 × 10⁸ metres per second (300,000 km/s).
What is the approximate speed of sound in air at room temperature?
About 343 m/s (roughly 330–340 m/s); much slower than light.
What is the difference between reflection and refraction of light?
Reflection is the bouncing back of light from a surface; refraction is the bending of light as it passes between media of different densities.
Which colours make up the visible spectrum (in order)?
Violet, Indigo, Blue, Green, Yellow, Orange, Red (VIBGYOR).
What type of lens is used to correct short-sightedness (myopia)?
A concave (diverging) lens.
What are the three methods of heat transfer?
Conduction, convection, and radiation.
What is the unit of frequency, and what does it measure for sound?
The hertz (Hz); it measures the number of vibrations (cycles) per second, determining the pitch of sound.
What is Ohm's Law?
Voltage = Current × Resistance (V = IR).
What are the SI units of electric current, voltage, and resistance?
Current in amperes (A), voltage in volts (V), and resistance in ohms (Ω).
What is the difference between a conductor and an insulator?
A conductor allows electric current to flow easily (e.g., copper); an insulator resists the flow of current (e.g., rubber, plastic).
What are the two poles of a magnet, and what is the rule of attraction?
North and south poles; like poles repel and unlike poles attract.

What is the difference between AC and DC current?
AC (alternating current) periodically reverses direction; DC (direct current) flows in one constant direction.
What is an element?
A pure substance made of only one kind of atom that cannot be broken down into simpler substances by chemical means (e.g., oxygen, gold).
What is the difference between a compound and a mixture?
A compound is two or more elements chemically combined in a fixed ratio (e.g., water); a mixture is a physical combination that can be separated by physical means (e.g., air).
What is the chemical formula of water and common salt?
Water is H₂O; common salt (sodium chloride) is NaCl.
What is the difference between an atom and a molecule?
An atom is the smallest unit of an element; a molecule is two or more atoms chemically bonded together.
What is the pH value range, and what does pH 7 indicate?
The pH scale ranges from 0 to 14; pH 7 indicates a neutral substance (neither acidic nor basic).
What is the difference between an acid and a base?
An acid releases H⁺ ions and has pH below 7 (sour taste); a base releases OH⁻ ions and has pH above 7 (bitter, slippery).
What is formed when an acid reacts with a base?
A salt and water (neutralization reaction).
What colour does litmus paper turn in acids and in bases?
Blue litmus turns red in acids; red litmus turns blue in bases.
What is rusting, and what two substances are required for it?
Rusting is the oxidation of iron to form iron oxide; it requires oxygen and water (moisture).
What gas is released when a metal reacts with an acid?
Hydrogen gas.
What is photosynthesis and its basic equation?
The process by which plants make food using sunlight: Carbon dioxide + Water → Glucose + Oxygen (in presence of sunlight and chlorophyll).
What is combustion?
A rapid chemical reaction of a substance with oxygen that produces heat and light (burning).
How many bones are in the adult human body, and how many chambers in the heart?
The adult human body has 206 bones; the heart has 4 chambers (two atria and two ventricles).
What is the function of red blood cells?
To carry oxygen (via haemoglobin) from the lungs to body tissues and carry carbon dioxide back.
Which organ is the largest in the human body, and which is the main organ of the excretory system?
The largest organ is the skin; the kidney is the main organ of the excretory system.
What is the function of the respiratory system?
To take in oxygen and remove carbon dioxide through breathing; gas exchange occurs in the lungs (alveoli).
Which deficiency causes scurvy, and which vitamin prevents it?
Scurvy is caused by a deficiency of Vitamin C (ascorbic acid).
Which vitamin deficiency causes night blindness, and which causes rickets?
Night blindness is caused by Vitamin A deficiency; rickets is caused by Vitamin D deficiency.
What causes diseases like malaria and dengue, and how are they transmitted?
Malaria is caused by a Plasmodium parasite via the female Anopheles mosquito; dengue is a viral disease spread by the Aedes mosquito.
What is the difference between a communicable and a non-communicable disease?
A communicable (infectious) disease spreads from person to person (e.g., TB, flu); a non-communicable disease does not spread (e.g., diabetes, cancer).
What gas do plants release during the day and absorb, and what is the role of chlorophyll?
Plants release oxygen and absorb carbon dioxide during photosynthesis; chlorophyll is the green pigment that absorbs sunlight for the process.
What is the difference between hardware and software?
Hardware is the physical components of a computer (e.g., keyboard, CPU); software is the set of programs/instructions that run on it (e.g., Windows, MS Word).
What is the CPU, and what is it called?
The Central Processing Unit, called the 'brain' of the computer; it processes instructions and performs calculations (contains the ALU and Control Unit).
What is the difference between RAM and ROM?
RAM (Random Access Memory) is temporary, volatile memory lost when power is off; ROM (Read Only Memory) is permanent, non-volatile memory.
Give two examples each of input and output devices.
Input devices: keyboard and mouse (also scanner, microphone). Output devices: monitor and printer (also speakers).
What is an operating system, and give two examples.
System software that manages computer hardware and software resources; examples include Windows, Linux, macOS, and Android.
What is the smallest unit of computer data, and how many bits make a byte?
The smallest unit is the bit (binary digit); 8 bits make 1 byte.
Which MS Office program is used for spreadsheets, and which for presentations?
MS Excel is used for spreadsheets (calculations and tables); MS PowerPoint is used for presentations (slides).
What is the difference between system software and application software?
System software runs and manages the computer itself (e.g., operating systems); application software performs specific user tasks (e.g., MS Word, browsers).
