Sample ECZ Science 5124 Practice Questions

Try these sample questions to test your ECZ Science 5124 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following is an SI base quantity with its correct base unit?

A.Mass — kilogram

B.Force — newton

C.Speed — metre per second

D.Energy — joule

Explanation: Mass is an SI base quantity and its base unit is the kilogram (kg). Length (metre), time (second) and thermodynamic temperature (kelvin) are also base quantities. Force, speed and energy are derived quantities, so the newton, metre per second and joule are derived units.

2Density is defined as

A.mass divided by volume

B.weight divided by volume

C.mass multiplied by volume

D.volume divided by mass

Explanation: Density is mass per unit volume, ρ = m / V. Combined-science papers expect the formula and consistent units such as g/cm³ or kg/m³. Weight is a force, so weight/volume is weight density, not the usual mass density used at this level.

3A copper block has mass 216 g and volume 24 cm³. What is its density?

A.5.2 g/cm³

B.9.0 g/cm³

C.8.0 g/cm³

D.0.11 g/cm³

Explanation: Density = mass / volume = 216 g / 24 cm³ = 9.0 g/cm³. Keep mass and volume in matching units. Copper’s density is about 9 g/cm³, which is a useful check that the calculation is in the right range.

4Which pair is a scalar quantity followed by a vector quantity?

A.Speed, velocity

B.Velocity, speed

C.Force, mass

D.Displacement, distance

Explanation: A scalar has magnitude only; a vector has magnitude and direction. Speed is scalar and velocity is the corresponding vector. Mass is scalar and force is a vector; displacement is a vector and distance is a scalar, so those pairs are in the wrong order.

5A bicycle increases its velocity from 4 m/s to 12 m/s in 8 s. What is its average acceleration?

A.0.5 m/s²

B.1.0 m/s²

C.1.5 m/s²

D.2.0 m/s²

Explanation: Acceleration = change in velocity / time = (12 − 4) m/s ÷ 8 s = 8 ÷ 8 = 1.0 m/s². The value is positive because the bicycle is speeding up in the stated direction.

6A learner has a mass of 50 kg. Taking g = 10 N/kg, what is the learner’s weight on Earth?

A.5 N

B.50 N

C.500 N

D.5000 N

Explanation: Weight is the gravitational force W = mg. With g = 10 N/kg, W = 50 × 10 = 500 N. Mass stays 50 kg; weight is the force in newtons. Combined-science papers in Zambia usually take g as 10 N/kg unless another value is given.

7Two forces of 12 N and 8 N act on a body along the same straight line but in opposite directions. What is the magnitude of the resultant force?

A.4 N

B.8 N

C.12 N

D.20 N

Explanation: Opposite forces on a straight line subtract. The resultant has magnitude 12 N − 8 N = 4 N and acts in the direction of the larger force. If the forces were in the same direction they would add to 20 N.

8A force of 20 N acts perpendicular to a door at a distance of 0.80 m from the hinges. What is the moment of the force about the hinges?

A.16 N m

B.20 N m

C.25 N m

D.0.04 N m

Explanation: Moment = force × perpendicular distance from the pivot = 20 N × 0.80 m = 16 N m. The force is already perpendicular to the line from the hinges, so no sine factor is needed at this level.

9Work is done when a force

A.moves its point of application in the direction of the force

B.acts on a stationary object that does not move

C.is balanced by an equal opposite force with no displacement

D.acts at right angles to a displacement of zero distance

Explanation: Work W = F × s when the force and the displacement are in the same direction. If the point of application does not move, the displacement is zero and no work is done, even if a large force is applied.

10A crane does 2400 J of work in 12 s. What is its useful power output?

A.20 W

B.200 W

C.240 W

D.28800 W

Explanation: Power is the rate of doing work: P = W / t = 2400 J / 12 s = 200 W. One watt is one joule per second. Multiplying work by time would give an energy-like product, not power.

ECZ Science 5124 Study Tips from Top Performers

1Use the CDC Grades 10–12 Science 5124 syllabus as a checklist: Paper 1 is physics-weighted and Paper 2 is chemistry-weighted.

2Practise calculations with a non-programmable calculator: density, W = mg, work and power, P = F/A, V = IR, moles and simple formulae.

3Learn the standard gas tests (hydrogen pop, oxygen relights a glowing splint, carbon dioxide turns limewater milky) and the water tests with anhydrous copper(II) sulfate and cobalt chloride paper.

4Treat life-process and ecology items as combined-science depth — cells, organs, photosynthesis, food chains — not a full Biology 5090 paper.

5Official papers include structured written questions; practise showing working and SI units, not only picking an MCQ option.

6Revise laboratory safety, apparatus choice and fair-test variables; school-based assessment is part of the syllabus scheme.
