✅ 2025 NECO Physics Objective Likely Questions and Answers

Question 1
Which of the following pairs of quantities is fundamental only?
A. Acceleration and length
B. Force and density
C. Time and length
D. Volume and mass
E. Work and temperature

• Correct Option: C
• Explanatory Answer: In physics, fundamental quantities are the basic quantities that are independent of others and from which derived quantities are obtained. The seven fundamental quantities are Mass (M), Length (L), Time (T), Electric Current (I), Thermodynamic Temperature (θ), Amount of Substance (mol), and Luminous Intensity (cd).
  • Options A, B, D, and E all contain at least one derived quantity (Acceleration, Force, Density, Volume, Work).
  • Option C, Time and Length, are both fundamental quantities.

Question 2
The following are examples of field force except
A. electric force.
B. electromagnetic force.
C. frictional force.
D. gravitational force.
E. magnetic force.

• Correct Option: C
• Explanatory Answer: A field force is a force that acts on an object at a distance, without any physical contact (e.g., gravity, electric force). A contact force requires physical touching. Frictional force is a contact force that arises when two surfaces slide or tend to slide over each other. All other options are field forces.

Question 3
A car travelled with a constant velocity of 10ms⁻¹ for 15s. Calculate the distance covered within this period.
A. 150.00 m
B. 25.00m
C. 5.00m
D. 1.50m
E. 0.67m
(Note: Option A is likely intended to be 150.00 m)

• Correct Option: A
• Explanatory Answer: For an object moving with constant velocity, the distance covered is calculated using the formula:
  Distance = Velocity × Time
  Given: Velocity (v) = 10 ms⁻¹ and Time (t) = 15 s.
  Distance = 10 m/s × 15 s = 150 m.

Question 4
The pair of quantities that consists of scalar and vector respectively is
A. acceleration and mass.
B. distance and force.
C. momentum and energy.
D. speed and time.
E. velocity and displacement.

• Correct Option: B
• Explanatory Answer: A scalar quantity has only magnitude (e.g., distance, speed, mass, energy, time). A vector quantity has both magnitude and direction (e.g., force, velocity, acceleration, momentum, displacement).
  • A: vector, scalar
  • B: scalar, vector (Correct order)
  • C: vector, scalar
  • D: scalar, scalar
  • E: vector, vector

Question 5
A body starts from rest and moves with a uniform acceleration ‘a’ until it attains a velocity ‘v’. The expression for the time taken to attain this velocity in terms of the given parameters is
A. v²/2a B. v/a C. v/2a D. 2v/a E. a/v

• Correct Option: B
• Explanatory Answer: This is derived from the first equation of motion: v = u + at.
  Given:
  Final velocity = v
  Initial velocity (starts from rest) u = 0
  Acceleration = a
  Time = t
  Substituting the values: v = 0 + at => v = at.
  Making ‘t’ the subject of the formula: t = v/a.

Question 6
A force of 150N is applied perpendicularly to the end of a 30cm spanner to remove a nut. Calculate the moment of the force.
A. 5.0 Nm B. 45.0 Nm C. 50.0 Nm D. 450.0 Nm E. 4500.0 Nm

• Correct Option: B
• Explanatory Answer: Moment of a force (or torque) is the product of the force and the perpendicular distance from the pivot to the line of action of the force.
  Moment = Force × Perpendicular Distance
  First, convert the distance to SI units: 30 cm = 0.30 m.
  Force (F) = 150 N
  Distance (r) = 0.30 m
  Moment = 150 N × 0.30 m = 45 Nm.

Question 7
An example of a body in stable equilibrium is a/an
A. ball resting on an inverted bowl.
B. cone resting on its base.
C. cylinder resting on its side.
D. egg resting on its apex.
E. sphere on a smooth horizontal table.

• Correct Option: B
• Explanatory Answer: A body is in stable equilibrium if, when slightly displaced, it returns to its original position. This occurs when its center of gravity is at the lowest possible point. A cone resting on its wide base has a low center of gravity and will return to this position if tilted slightly.
  • A, D: Unstable equilibrium (will not return).
  • C, E: Neutral equilibrium (will stay in the new position).

Question 8
A ball kicked at an angle 40° to the horizontal hits the ground 3s later. Calculate the initial velocity of the ball neglecting air resistance [g = 10ms⁻²]
A. 93.3ms⁻¹ B. 46.7ms⁻¹ C. 23.3ms⁻¹ D. 19.6ms⁻¹ E. 4.8ms⁻¹

Correct Option: C

Explanatory Answer: The formula for the time of flight (T) of a projectile is T = (2u sinθ) / g.
We are given: T = 3 s, θ = 40°, g = 10 ms⁻². We need to find the initial velocity, u.
Rearranging the formula: u = (T × g) / (2 sinθ)
u = (3 × 10) / (2 × sin(40°))
u = 30 / (2 × 0.6428)
u = 30 / 1.2856 ≈ 23.33 ms⁻¹

Question 9
A body vibrates with simple harmonic motion at a frequency of 100Hz. If the amplitude of vibration is 5cm, calculate its linear speed.
A. 3140.0ms⁻¹ B. 1570.0ms⁻¹ C. 31.4ms⁻¹ D. 15.7ms⁻¹ E. 6.3ms⁻¹

• Correct Option: C
• Explanatory Answer: The question asks for the maximum linear speed (v_max) in SHM. The formula is v_max = Aω, where A is the amplitude and ω is the angular frequency.
  Angular frequency ω = 2πf.
  Given: f = 100 Hz, A = 5 cm = 0.05 m, π = 3.14.
  ω = 2 × 3.14 × 100 = 628 rad/s.
  v_max = Aω = 0.05 m × 628 rad/s = 31.4 m/s.

Question 10
Which of the following sets comprises first and second order levers respectively?
A. Claw hammer and wheelbarrow
B. Forceps and claw hammer
C. Plier and forearm
D. Scissors and crowbar
E. Wheelbarrow and crowbar

Correct Option: A

Explanatory Answer: Levers are classified by the relative positions of the Fulcrum (F), Effort (E), and Load (L).

First Order: Fulcrum is in the middle (e.g., crowbar, scissors, pliers, claw hammer when pulling a nail).

Second Order: Load is in the middle (e.g., wheelbarrow, bottle opener).

Third Order: Effort is in the middle (e.g., forceps, fishing rod, human forearm).
Option A: Claw hammer (1st order) and Wheelbarrow (2nd order) is the correct pair.

Question 11
Which of the following energy resources can be used to generate electricity without the use of a turbine?
A. Nuclear B. Solar C. Tide D. Water E. Wind

• Correct Option: B
• Explanatory Answer: Solar energy, specifically through photovoltaic (PV) cells, converts sunlight directly into electricity via the photoelectric effect. All the other options (Nuclear, Tidal, Hydroelectric/Water, Wind) use their energy source to heat water or move a fluid, which then spins a turbine connected to a generator.

Question 12
A body of mass 3 kg moving with a velocity of 10 ms⁻¹ collides with a stationary body of mass 1.5 kg. If the two bodies move together after the impact, calculate their common velocity.
A. 0.5 ms⁻¹ B. 1.5 ms⁻¹ C. 6.7 ms⁻¹ D. 10.0 ms⁻¹ E. 20.0 ms⁻¹

• Correct Option: C
• Explanatory Answer: This is a problem of inelastic collision, where momentum is conserved.
  Let m₁, u₁ be the mass and initial velocity of the first body.
  Let m₂, u₂ be the mass and initial velocity of the second body.
  Let v be their common final velocity.
  Conservation of Momentum: m₁u₁ + m₂u₂ = (m₁ + m₂)v
  Given: m₁ = 3 kg, u₁ = 10 ms⁻¹, m₂ = 1.5 kg, u₂ = 0 ms⁻¹ (stationary).
  (3 × 10) + (1.5 × 0) = (3 + 1.5)v
  30 = 4.5v
  v = 30 / 4.5 ≈ 6.67 ms⁻¹

Question 13
How much heat is required to convert 60g of water at 90°C to steam at 100°C? [Specific latent heat of vaporization of water = 2.26 × 10⁶ Jkg⁻¹, specific heat capacity of water = 4.2 x 10³ Jkg⁻¹K⁻¹]
A. 2.52 × 10³J B. 5.40 x 10³J C. 1.36 × 10⁵J D. 1.38 × 10⁵J E. 1.58 × 10⁵J

• Correct Option: D
• Explanatory Answer: This requires a two-step calculation. Mass m = 60g = 0.06 kg.
  Step 1: Heat required to raise water temperature from 90°C to 100°C.
  Q₁ = mcΔT = 0.06 kg × (4.2 × 10³ Jkg⁻¹K⁻¹) × (100 – 90)K
  Q₁ = 0.06 × 4200 × 10 = 2520 J
  Step 2: Heat required to convert water at 100°C to steam at 100°C (latent heat).
  Q₂ = mLᵥ = 0.06 kg × (2.26 × 10⁶ Jkg⁻¹)
  Q₂ = 135,600 J
  Total Heat: Q_total = Q₁ + Q₂ = 2520 J + 135,600 J = 138,120 J = 1.38 × 10⁵ J.

Question 14
The temperature of land rises faster than that of the sea when heated by the sun because land
A. has larger surface area than the sea.
B. has lower specific heat capacity than the sea.
C. is a poorer absorber of heat.
D. is denser than the sea.
E. receives higher quantity of heat energy than the sea.

• Correct Option: B
• Explanatory Answer: Specific heat capacity is the amount of heat required to raise the temperature of 1kg of a substance by 1K. Water has a very high specific heat capacity, meaning it requires a lot of energy to change its temperature. Land (soil, rock) has a much lower specific heat capacity, so the same amount of solar energy causes a much larger temperature increase.

Question 15
Which of the following factors will affect both boiling point and rate of evaporation of a liquid?
A. Exposed surface area B. Impurity C. Nature of the liquid D. Pressure E. Wind

• Correct Option: D
• Explanatory Answer:
  • Boiling point is defined as the temperature at which the vapor pressure of a liquid equals the external (atmospheric) pressure. Therefore, changing the external pressure changes the boiling point.
  • Rate of evaporation also depends on pressure. Lower external pressure makes it easier for molecules to escape the liquid surface, increasing the rate of evaporation.
  • Impurity affects boiling point but has a less direct effect on evaporation rate compared to pressure. Surface area and wind only affect the rate of evaporation, not the boiling point.
