The relationship between escape velocity and atmosphere is not a direct one. Escape velocity depends upon the local gravity, which is consequential to the planet's mass and distance. The existence of an atmosphere also can depend upon mass, since with too little mass a planet doesn't hold on well to its atmosphere.
Different planets have different escape speeds due to variations in their gravitational pull. A planet with a higher mass will have a higher escape speed, as the force of gravity is stronger. Escape speed is the velocity needed to break free from a planet's gravitational field and overcome the gravitational pull.
Yes, all planets have different gravitation pulls. The gravity on one planet differs from another planet because of the mass of the planet. According to universal gravitation, a planet with a larger mass will have more gravity than that of a smaller planet. For example, Neptune's free-fall acceleration is 11 m/s compared to that of Earth's which is 10 m/s (rounded). Therefore, Neptune has more mass than Earth and a stronger gravitational pull.
Each planet is a different size with unique densities and overall masses. These are the properties that influence the escape velocity. Generally, a more massive planet will have a higher escape velocity, more speed is required to leave the stronger gravitational field that comes with the higher mass. But size and density also have to be considered.
That's because the escape speed depends on the planet's mass and radius.
The factors are :
M = planet mass in kg
r = object distance from planet centre in metres (usually the distance from the planet centre to the surface, the planet's radius).
Then, using the "gravitational constant", we can derive the escape speed.
G = 6.67384 x 10-11 (the gravitational constant)
The escape speed (in m/s) is then the square root of (2GM)/r.
The speed required to go against gravity depends on the force needed to overcome it. In general, you would need to travel at least the escape velocity, which is about 11.2 km/s on Earth, to go against gravity and leave the planet's gravitational pull. This speed varies depending on the celestial body you are considering.
To find the average velocity when there are two different speeds, you can use the formula: average velocity = total distance traveled / total time taken. Simply calculate the total distance traveled and total time taken for the two different speeds, and plug these values into the formula to find the average velocity.
Light travels at different speeds in different materials because its speed is influenced by the material's refractive index, which is a measure of how much the material slows down light. When light enters a material with a higher refractive index, it is slowed down more compared to when it travels through a material with a lower refractive index. This difference in speed causes light to travel at different speeds in different materials.
Jupiter has the greatest escape velocity in our solar system, due to its large mass and strong gravitational pull. The escape velocity on Jupiter is about 59.5 km/s, which is higher than any other planet in our solar system.
Brownian motion is a type of random motion in which particles move in different directions and at different speeds due to collisions with other particles in the surrounding medium. This phenomenon was first observed by Robert Brown in the early 19th century.
It was Johannes Kepler who produced the theory of the planets' positions and speeds which is accepted today.
Planets orbit the sun at different speeds because they are at varying distances from the sun. According to Kepler's laws of planetary motion, planets closer to the sun have faster orbital speeds, while those farther away have slower speeds. This is due to the gravitational force exerted by the sun, which is stronger on planets closer to it.
Yes. It is different for different planets etc. Escape velocity on earth is different than escape velocity on Jupiter.
The planets move on little circles that move on bigger circles.
The question is meaningless; different dwarf planets move at different speeds.
Planets have different day lengths due to variations in their rotation speeds and sizes. Planets closer to the Sun, like Mercury, have shorter day lengths because they rotate faster. Larger planets, such as Jupiter, have longer day lengths due to their slower rotation speeds.
Yes, all of them do, though at different speeds.

The Jovian planets have much higher escape velocities.
Planets complete their orbits at different times because they are at different distances from the Sun and travel at different speeds. This is due to Kepler's laws of planetary motion, where planets closer to the Sun have shorter orbital periods, while those farther away take longer to complete their orbits.
