Sample Tamil Nadu SSLC Science Practice Questions

Try these sample questions to test your Tamil Nadu SSLC Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1SI unit of force is:
A.Joule
B.Newton
C.Watt
D.Pascal
Explanation: Force is measured in newton (N). One newton is the force that gives a 1 kg mass an acceleration of 1 m/s² (1 N = 1 kg·m/s²).
2The product of mass and velocity of a body is called:
A.Acceleration
B.Force
C.Momentum
D.Impulse
Explanation: Linear momentum p = m × v. It is a vector quantity and has SI unit kg·m/s.
3According to Newton’s first law of motion, a body continues in its state of rest or uniform motion unless acted upon by:
A.Inertia
B.An unbalanced external force
C.Friction only
D.Gravity only
Explanation: Newton’s first law (law of inertia): a body remains at rest or in uniform straight-line motion unless an unbalanced external force acts on it.
4The SI unit of electric current is:
A.Volt
B.Ohm
C.Ampere
D.Coulomb
Explanation: Electric current is measured in ampere (A). One ampere is one coulomb of charge flowing per second.
5Ohm’s law states that, at constant temperature, V is directly proportional to:
A.Resistance R
B.Current I
C.Power P
D.Charge Q
Explanation: Ohm’s law: V ∝ I at constant temperature for an ohmic conductor, so V = IR.
6The device that measures electric current in a circuit is a:
A.Voltmeter
B.Ammeter
C.Galvanometer only used for voltage
D.Wattmeter
Explanation: An ammeter measures current and is connected in series with the circuit component.
7Among common transparent media, light travels fastest in:
A.Water
B.Glass
C.Air
D.Diamond
Explanation: Among common media, the speed of light is highest in air (closest to vacuum) and lower in denser optical media such as water, glass, and diamond.
8The angle of incidence equals the angle of reflection. This is a law of:
A.Refraction
B.Reflection
C.Diffraction
D.Dispersion
Explanation: Laws of reflection: (1) incident ray, reflected ray and normal lie in one plane; (2) angle of incidence = angle of reflection.
9Heat energy is measured in SI units of:
A.Celsius
B.Joule
C.Calorie only
D.Kelvin
Explanation: Heat is a form of energy and is measured in joules (J) in SI. Calorie is a non-SI unit sometimes still used.
10Sound is a: Choose the correct answer.
A.Electromagnetic wave that needs no medium
B.Mechanical longitudinal wave that needs a medium
C.Transverse wave that travels in vacuum
D.Particle stream of electrons
Explanation: Sound is a mechanical longitudinal wave. It needs a material medium (solid, liquid, or gas) and cannot travel in vacuum.
