    What happens to the wavelength of light when it approaches a massive object?

    • It decreases.

    • It increases.

    • It remains unchanged.

    • It ceases to exist.

    Correct Answer
    A. It decreases.
    Explanation
    The wavelength of light decreases when it approaches a massive object due to gravitational redshift. This effect is caused by the distortion of space-time by the massive object's gravitational field.

    Rate this question:

  • 3. 

    Which of the following is NOT a predicted consequence of general relativity?

    • Gravitational time dilation

    • Gravitational waves

    • Gravitational lensing

    • Gravitational acceleration

    Correct Answer
    A. Gravitational acceleration
    Explanation
    Gravitational acceleration is not a predicted consequence of general relativity. It is described by Newtonian mechanics rather than Einstein's theory of general relativity.

    Rate this question:

  • 4. 

    What is the value of Earth's gravitational acceleration approximately?

    • 9.8 m/s^2

    • 3.14 m/s^2

    • 6.67 x 10^-11 Nm^2/kg^2

    • 2.718 m/s^2

    Correct Answer
    A. 9.8 m/s^2
    Explanation
    The value of Earth's gravitational acceleration is approximately 9.8 meters per second squared (m/s^2). This value represents the acceleration experienced by objects near Earth's surface due to gravity.

    Rate this question:

  • 5. 

    What happens to the gravitational force between two objects if the distance between them is doubled?

    • It is halved.

    • It quadruples.

    • It doubles.

    • It remains unchanged.

    Correct Answer
    A. It is halved.
    Explanation
    If the distance between two objects is doubled, the gravitational force between them is halved. The force of gravity decreases with the square of the distance.

    Rate this question:

  • 6. 

    What is the maximum possible escape velocity in the universe?

    • The speed of light

    • Twice the speed of light

    • The speed of sound

    • Escape velocity has no maximum value

    Correct Answer
    A. Escape velocity has no maximum value
    Explanation
    Escape velocity has no maximum value. The velocity required to escape the gravitational pull of an object can be theoretically infinite if sufficient energy is applied.

    Rate this question:

  • 7. 

    What are gravitational waves?

    • Ripples in the fabric of space-time caused by accelerating massive objects

    • The force exerted by Earth on objects near its surface

    • The resistance of an object to changes in its motion

    • A measure of the amount of matter in an object

    Correct Answer
    A. Ripples in the fabric of space-time caused by accelerating massive objects
    Explanation
    Gravitational waves are disturbances in the curvature of space-time caused by the acceleration of massive objects. These waves were predicted by Albert Einstein's theory of general relativity and were first directly observed in 2015, confirming a key aspect of Einstein's theory. Gravitational waves carry information about their origins and the nature of gravity itself.

    Rate this question:

  • 8. 

    What effect does gravitational pull have on time?

    • It slows down time.

    • It speeds up time.

    • It has no effect on time.

    • It reverses the direction of time.

    Correct Answer
    A. It slows down time.
    Explanation
    Gravitational pull can slow down time. This phenomenon, known as time dilation, occurs when an object is in a region with stronger gravitational forces. It is a consequence of Einstein's theory of general relativity.

    Rate this question:

  • 9. 

    What does the term 'g-force' refer to?

    • The force of gravity acting on an object

    • The acceleration experienced by an object due to gravity

    • The ratio of an object's mass to its volume

    • The force exerted by an object on a supporting surface

    Correct Answer
    A. The acceleration experienced by an object due to gravity
    Explanation
    The term 'g-force' refers to the acceleration experienced by an object due to gravity. It is commonly used to describe the forces experienced by astronauts during takeoff, landing, or other high-acceleration maneuvers.

    Rate this question:

  • 10. 

    Which factor most affects the strength of gravitational pull between two objects?

    • Distance between the objects

    • Mass of the larger object

    • Mass of the smaller object

    • Speed of the objects

    Correct Answer
    A. Mass of the larger object
    Explanation
    The mass of the larger object most affects the strength of gravitational pull between two objects. The greater the mass of an object, the stronger its gravitational attraction will be.
