Which of the following is true about Gravitational Field?

• Gravitational fields do not affect small masses.
• Gravitational fields act in all directions and between objects of mass.
• Gravitational fields only act vertically.
• Gravitational fields are only present in space.

Which correctly describes the difference of gravitational law to law of relativity?

• Both laws describe the same phenomenon in different terms without any differences.
• The law of gravitation only applies to large celestial bodies.
• The law of gravitation describes forces between masses, while the law of relativity explains gravity as the curvature of spacetime.
• The law of relativity states that gravity is a force that acts instantaneously.

Which of the following correctly describe the variations on the value of g in the surface of the earth?

• g is unaffected by geological structures.
• g varies with altitude, latitude, and local geological structures.
• g only varies with temperature.
• g is constant across the Earth's surface.

What law of explains why the sun takes only one focus in the solar system?

• Kepler's First Law (Law of Ellipses)
• Newton's Law of Universal Gravitation
• Kepler's Third Law (Law of Harmonies)
• Kepler's Second Law (Law of Equal Areas)

What happens to the speed of the earth as it moves closer to the sun?

• The speed of the Earth increases as it moves closer to the Sun.
• The speed of the Earth fluctuates randomly as it orbits the Sun.
• The speed of the Earth remains constant regardless of its distance from the Sun.
• The speed of the Earth decreases as it moves closer to the Sun.

What happens when apogee is evident?

• The object is at its closest distance to the central body.
• The object is in a stable orbit around the central body.
• The object is experiencing maximum gravitational pull from the central body.
• The object is at its maximum distance from the central body.

which of the following best describe Periodic motion?

• Periodic motion is a type of linear motion.
• Periodic motion occurs only in one direction.
• Periodic motion is random and unpredictable.
• Periodic motion is motion that repeats at regular intervals.

Which of the following is an example of periodic motion?

• Linear motion
• Pendulum motion
• Circular motion
• Rotational motion

What are the conditions of harmonic motion?

• A damping force that increases with displacement
• A constant force acting in the same direction as displacement
• The conditions of harmonic motion are: a restoring force proportional to displacement, periodic motion, and minimal damping.
• Non-periodic motion with increasing amplitude

Which of the following is an example of simple harmonic motion?

• A pendulum swinging in a circular path.
• A child spinning on a merry-go-round.
• A car driving in a straight line.
• A mass on a spring oscillating back and forth.
