Sample Yamanashi Entrance Science Practice Questions

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

1A car travels 120 km in 2 hours at constant speed. What is its average speed (速さ)?
A.60 km/h
B.30 km/h
C.120 km/h
D.240 km/h
Explanation: Average speed is distance divided by time: v = d/t. Substituting gives 120 km ÷ 2 h = 60 km/h. When speed is constant, average speed equals the constant speed.
2Density (密度) is defined as which relationship between mass and volume?
A.mass × volume
B.mass ÷ volume
C.volume ÷ mass
D.mass + volume
Explanation: Density ρ equals mass m divided by volume V: ρ = m/V. SI units are typically g/cm³ or kg/m³. A denser object packs more mass into the same volume.
3In a simple series circuit, a battery of 6 V is connected to a single resistor of 3 Ω. What is the current (電流) through the resistor?
A.0.5 A
B.9 A
C.2 A
D.18 A
Explanation: Ohm’s law states V = IR, so I = V/R. With V = 6 V and R = 3 Ω, I = 6/3 = 2 A. Current is the same at every point in a single series loop with one resistor.
4Which statement about sound (音) is correct?
A.Sound can travel through a perfect vacuum.
B.Sound travels faster in air than in water.
C.Higher pitch always means greater loudness.
D.Sound is a longitudinal mechanical wave that needs a medium.
Explanation: Sound is a longitudinal mechanical wave of compressions and rarefactions. It requires a material medium such as air, water, or solids, so it cannot propagate in a vacuum.
5A force of 10 N acts on an object for a displacement of 3 m in the same direction as the force. How much work (仕事) is done?
A.30 J
B.3 J
C.7 J
D.13 J
Explanation: Work W = F × d when force and displacement are parallel: 10 N × 3 m = 30 J. The joule (J) is the SI unit of work and energy.
6On a plane mirror, the angle of incidence equals which angle?
A.The angle of refraction
B.The angle of reflection (反射)
C.90° always
D.Twice the reflected ray angle
Explanation: The law of reflection states that the angle of incidence equals the angle of reflection, both measured from the normal to the surface. Plane mirrors form virtual, upright images of the same size.
7Which unit is the SI unit of electric current?
A.Volt (V)
B.Ohm (Ω)
C.Ampere (A)
D.Watt (W)
Explanation: Current is measured in amperes (A). Voltage is in volts (V), resistance in ohms (Ω), and power in watts (W). Linking them: P = VI and V = IR.
8Pressure (圧力) on a surface equals force divided by what?
A.Mass
B.Volume
C.Density
D.Area
Explanation: Pressure p = F/A, force perpendicular to a surface divided by the contact area. The same force on a smaller area produces higher pressure, which is why sharp blades cut more easily.
9An object of mass 200 g occupies a volume of 50 cm³. What is its density?
A.4 g/cm³
B.0.25 g/cm³
C.10 g/cm³
D.250 g/cm³
Explanation: Density ρ = m/V = 200 g ÷ 50 cm³ = 4 g/cm³. Keep units consistent; here grams and cubic centimeters are a common junior-high pairing.
10A box exerts a force of 40 N on the floor over an area of 0.20 m². What pressure does it apply?
A.8 Pa
B.200 Pa
C.80 Pa
D.2000 Pa
Explanation: Pressure p = F/A = 40 N ÷ 0.20 m² = 200 Pa. One pascal equals one newton per square meter.

Yamanashi Entrance Science Study Tips from Top Performers

1Balance all four science domains — weak earth science or chemistry often costs easy points.
2Practise reading tables, graphs, and simple experiment diagrams before choosing a conclusion.
3Memorise core formulas (density, pressure, Ohm's law, speed) and when each applies.
4For biology, connect cell → tissue → organ → system rather than memorising isolated terms.
5For earth science, link weather maps, plate boundaries, and the water cycle to observable outcomes.
6Time mixed 45–50 minute sets and write short Japanese explanations even when using MCQs.
