PHYSICS I & II EXAM LATEST 2026 UPDATE 100
QUESTIONS AND DETAILED VERIFIED ANSWERS
FROM ACTUAL EXAMS TEST GRADE A+ .
1. What is the SI unit of force?
Answer: Newton (N)
Rationale: Force is defined as mass × acceleration, giving kg·m/s², which is called a
Newton.
2. Newton’s First Law is also known as?
Answer: Law of Inertia
Rationale: It describes the tendency of an object to resist changes in its state of
motion.
3. What is the acceleration due to gravity on Earth?
Answer: 9.8 m/s²
Rationale: This is the standard average gravitational acceleration near Earth’s
surface.
4. Work is defined as?
Answer: Force × Distance × cosθ
Rationale: Only the component of force in the direction of motion does work.
5. Unit of power is?
,Answer: Watt (W)
Rationale: Power is the rate of doing work (Joules per second).
6. Momentum is given by?
Answer: p = mv
Rationale: Momentum depends on both mass and velocity.
7. Unit of momentum is?
Answer: kg·m/s
Rationale: Derived from mass × velocity.
8. Newton’s Second Law states?
Answer: F = ma
Rationale: Force is proportional to rate of change of momentum.
9. Energy stored in a stretched spring is?
Answer: ½kx²
Rationale: Elastic potential energy depends on displacement squared.
10. Kinetic energy formula is?
Answer: ½mv²
Rationale: Energy due to motion depends on mass and square of velocity.
11. SI unit of energy is?
, Answer: Joule (J)
Rationale: Work and energy share the same unit.
12. Ohm’s Law is?
Answer: V = IR
Rationale: Voltage is directly proportional to current for a conductor.
13. Unit of electric current is?
Answer: Ampere (A)
Rationale: It measures charge flow per second.
14. Electric power formula is?
Answer: P = VI
Rationale: Power is product of voltage and current.
15. Resistance is measured in?
Answer: Ohm (Ω)
Rationale: It quantifies opposition to current flow.
16. Frequency unit is?
Answer: Hertz (Hz)
Rationale: One cycle per second defines frequency.
17. Wave speed equation is?
