What is escape velocity?
-
The velocity required to escape Earth's gravitational pull
-
The velocity at which an object falls when dropped from a height
-
The constant acceleration experienced by an object in free fall
-
The maximum acceleration an object can undergo without breaking apart
Correct Answer
A. The velocity required to escape Earth's gravitational pullExplanation
Escape velocity is the minimum velocity an object needs to break free from the gravitational attraction of a massive body, such as the Earth. It is the speed at which the kinetic energy of an object equals the gravitational potential energy, allowing it to overcome the gravitational pull and move away indefinitely. On Earth, it is approximately 11.2 kilometers per second.Rate this question:

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:

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:

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 accelerationExplanation
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:

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^2Explanation
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:

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 gravityExplanation
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:

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 objectExplanation
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.Rate this question:
-
- 9.
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:
-
- 10.
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 valueExplanation
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:
