Forces and Motion in Celestial Bodies Quiz

Gravitational force is responsible for the attraction between objects with mass, keeping celestial bodies in orbit around a central mass.

The SI unit of force is the Newton, named after Sir Isaac Newton, and is defined as the force required to accelerate a one-kilogram mass at a rate of one meter per second squared.

Frictional force opposes the motion of an object through a fluid, acting to slow down or stop the object's movement.

Frictional force is the force that opposes the relative motion or tendency of motion between two surfaces in contact.

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction, describing the conservation of momentum.

Perihelion refers to the point in an orbit where a celestial body is closest to the central mass it is orbiting, commonly used for objects orbiting the Sun.

Newton's First Law of Motion states that an object will remain at rest or in uniform motion unless acted upon by an external force.

Jupiter is known for its Great Red Spot, a persistent high-pressure storm in its atmosphere, which has been observed for centuries.

In celestial mechanics, the axis is the imaginary line around which a celestial body, such as a planet, rotates.

Isaac Newton is credited with discovering the three laws of motion and the law of universal gravitation, laying the foundation for classical mechanics.

Escape velocity from Earth's surface is the minimum speed an object must reach to break free from Earth's gravitational attraction, and it is approximately 11.2 kilometers per second.

Johannes Kepler formulated the laws of planetary motion, providing a mathematical description of the orbits of planets around the Sun.

The Doppler Effect explains how the frequency or wavelength of a wave changes as an observer moves relative to the source of the wave.

Dark energy is the hypothetical force driving the accelerated expansion of the universe, counteracting gravitational forces.

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting upon the object and inversely proportional to the object's mass.
