Berlin Abitur Physics 3. PF (GK) Practice Questions - Berlin Abitur Physics - third examination subject (3. Prüfungsfach, Grundkurs Pool) Exam - Berlin Abitur Physics 3. PF (GK) Practice Questions - Berlin Abitur Physics - third examination subject (3. Prüfungsfach, Grundkurs Pool) Exam

Question 1

Two 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?

It is halved It stays the same because gravity is always equal on both bodies It doubles It becomes four times as large

Correct Answer:

It doubles

Question 2

Which value is the best approximation for the gravitational field strength (Ortsfaktor) g at the Earth's surface?

9.81 N/kg 1.62 N/kg 6.67 × 10⁻¹¹ N·m²/kg² 24.8 N/kg

Correct Answer:

9.81 N/kg

Question 3

What does Kepler's first law (1. Keplersches Gesetz) state about planetary orbits?

Planets move on circles with the Sun at the exact center A line from the Sun to a planet sweeps out equal areas in equal times The squares of the orbital periods are proportional to the cubes of the semi-major axes Planets move on ellipses with the Sun at one of the two foci

Correct Answer:

Planets move on ellipses with the Sun at one of the two foci

Question 4

A geostationary satellite appears fixed above one point of the Earth. Which conditions must its orbit satisfy?

Polar orbit with a period of 90 minutes Circular orbit above the equator with an orbital period of 24 hours in the direction of Earth's rotation Elliptical orbit above the poles with a period of 12 hours Any orbit at an altitude of exactly 400 km

Correct Answer:

Circular orbit above the equator with an orbital period of 24 hours in the direction of Earth's rotation

Question 5

Astronauts 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?

The ISS is outside the Earth's gravitational field The atmosphere at that altitude cancels the gravitational force The centrifugal force exactly cancels gravity only at the orbit's center of mass The ISS and its crew are in continuous free fall around the Earth, so no supporting force acts on the astronauts

Correct Answer:

The ISS and its crew are in continuous free fall around the Earth, so no supporting force acts on the astronauts
