1Two point masses attract each other with the gravitational force F. If one of the two masses is doubled while the distance stays the same, what happens to the force?
A.It is halved
B.It stays the same because gravity is always equal on both bodies
C.It doubles
D.It becomes four times as large
Explanation: Newton's law of gravitation states F = G·m1·m2/r², so the force is directly proportional to each mass. Doubling one mass therefore doubles the force. This kind of proportional reasoning (Proportionalitätsbetrachtung) is a core skill tested in Anforderungsbereich I and II.
2Which value is the best approximation for the gravitational field strength (Ortsfaktor) g at the Earth's surface?
A.9.81 N/kg
B.1.62 N/kg
C.6.67 × 10⁻¹¹ N·m²/kg²
D.24.8 N/kg
Explanation: At the Earth's surface g ≈ 9.81 N/kg (equivalently 9.81 m/s²). The value 6.67 × 10⁻¹¹ N·m²/kg² is the universal gravitational constant G, not a field strength, and 1.62 N/kg is the value on the Moon. Distinguishing G from g is a classic Grundkurs checkpoint.
3What does Kepler's first law (1. Keplersches Gesetz) state about planetary orbits?
A.Planets move on circles with the Sun at the exact center
B.A line from the Sun to a planet sweeps out equal areas in equal times
C.The squares of the orbital periods are proportional to the cubes of the semi-major axes
D.Planets move on ellipses with the Sun at one of the two foci
Explanation: Kepler's first law says each planet moves on an ellipse with the Sun located at one focus, not the center. The equal-areas statement is the second law (Flächensatz), and the T² ∝ a³ relation is the third law, which links orbits quantitatively. In the Berlin Rahmenlehrplan these laws anchor the Q1 theme Gravitation.
4A geostationary satellite appears fixed above one point of the Earth. Which conditions must its orbit satisfy?
A.Polar orbit with a period of 90 minutes
B.Circular orbit above the equator with an orbital period of 24 hours in the direction of Earth's rotation
C.Elliptical orbit above the poles with a period of 12 hours
D.Any orbit at an altitude of exactly 400 km
Explanation: A satellite only appears stationary if its orbital period equals the Earth's rotation period (about 24 h) and it orbits in the equatorial plane in the same sense as the Earth rotates; this fixes the radius at about 42,000 km from the Earth's center. A polar or elliptical orbit would make the satellite drift across the sky.
5Astronauts aboard the ISS float 'weightlessly', although the Earth's gravity at the ISS altitude is still about 90% of its surface value. What is the correct physical explanation?
A.The ISS is outside the Earth's gravitational field
B.The atmosphere at that altitude cancels the gravitational force
C.The centrifugal force exactly cancels gravity only at the orbit's center of mass
D.The ISS and its crew are in continuous free fall around the Earth, so no supporting force acts on the astronauts
Explanation: Schwerelosigkeit in orbit results from permanent free fall: the ISS and everything inside it accelerate toward the Earth with the same centripetal acceleration, so the station exerts no normal force on the astronauts. Gravity is very much present — it is precisely what keeps the station on its curved path.
6Two asteroids attract each other with force F. If the distance between their centers is doubled, the gravitational force becomes…
A.F/4
B.F/2
C.2F
D.unchanged, because mass does not depend on distance
Explanation: Newton's law of gravitation contains a 1/r² dependence: F = G·m1·m2/r². Doubling r therefore reduces the force to one quarter. This inverse-square law (Fernwirkung mit 1/r²-Abnahme) parallels the Coulomb law for electric charges.
7Calculate the approximate orbital speed of a satellite on a circular orbit 400 km above the Earth's surface (Earth radius 6,371 km, Earth mass 5.97 × 10²⁴ kg, G = 6.67 × 10⁻¹¹ N·m²/kg²).
A.About 1.0 km/s
B.About 3.6 km/s
C.About 11.2 km/s
D.About 7.7 km/s
Explanation: For a circular orbit, gravitational force supplies the centripetal force, giving v = √(G·M/r) with r = 6,371 km + 400 km = 6.77 × 10⁶ m. Inserting values: v = √(3.98 × 10¹⁴ m³/s² ÷ 6.77 × 10⁶ m) ≈ √(5.9 × 10⁷ m²/s²) ≈ 7.7 km/s. This is the typical speed of low-Earth-orbit satellites such as the ISS.
8Planet B has a semi-major axis four times larger than planet A around the same star. According to Kepler's third law, how do their orbital periods compare?
A.Planet B's period is 4 times longer
B.Planet B's period is 8 times longer
C.Planet B's period is 16 times longer
D.Planet B's period is 64 times longer
Explanation: Kepler's third law states T² ∝ a³. With a four times larger, a³ grows by 4³ = 64, so T² grows by 64 and T grows by √64 = 8. The period of planet B is therefore eight times that of planet A.
9A space probe is located at a distance of two Earth radii from the Earth's center (i.e., one Earth radius above the surface). What gravitational acceleration does it experience approximately?
A.9.81 m/s², because gravity is constant near Earth
B.4.91 m/s²
C.2.45 m/s²
D.0 m/s², because it is already in space
Explanation: The field strength of a spherical mass falls off with 1/r² measured from the center. At r = 2·R_E the acceleration is g/4 ≈ 9.81/4 ≈ 2.45 m/s². Note that the relevant distance is measured from the Earth's center, not from the surface — a common Fehlerquelle in Abitur tasks.
10Which statement correctly compares the Coulomb force between two charges with the gravitational force between two masses?
A.Both follow a 1/r² distance law, but the Coulomb force can be attractive or repulsive while gravity is always attractive
B.Gravity can be repulsive for antimatter, the Coulomb force cannot
C.The Coulomb force follows a 1/r law, gravity a 1/r² law
D.Both forces are always attractive and both follow a 1/r law
Explanation: Both laws have the same mathematical structure F ∝ 1/r² and are proportional to the product of the two quantities (masses or charges). The decisive difference is that charges come in two signs, so the Coulomb force can attract or repel, whereas mass is only positive and gravity only attracts. Such Vergleich tasks between field models are typical for Anforderungsbereich II.
