In order for a body to escape the gravitational pull of the Earth, it needs to be thrown up with an initial velocity equal to or greater than the escape velocity of around 11.2 km/s. This velocity allows the object to overcome the gravitational pull of the Earth and continue traveling away from it indefinitely.

Does escape velocity depend upon height from which it is projected?
Yes, escape velocity does depend on the height from which an object is projected. The higher the height, the lower the escape velocity required because the gravitational force weakens with distance from the center of the planet.
What is the escape velocity of mercury?
The escape velocity of Mercury is about 4.3 km/s, which is the speed an object must reach to break free from Mercury's gravitational pull and move into space.
What speed do rockets break earths gravitational pull?
The speed required for a rocket to break Earth's gravitational pull and achieve orbit is known as the escape velocity, which is about 11.2 km/s (25,000 mph) for Earth. Rocket engines are typically designed to achieve escape velocity during launch in order to overcome Earth's gravitational pull.
Why you must study escape velocity?
Studying escape velocity is important to understand the minimum velocity needed for an object to break free from a planet or celestial body's gravitational pull. This knowledge is crucial for space exploration, satellite launches, and designing spacecraft trajectories to ensure they can reach their intended destinations. Understanding escape velocity also helps in calculating fuel requirements and optimizing mission plans for space travel.
How is escape velocity obtained?
Escape velocity is the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or moon. It is typically achieved by launching a spacecraft with sufficient speed to overcome the gravitational force, allowing it to move away without being pulled back. The formula to calculate escape velocity is derived from the relationship between an object's kinetic and potential energy.
You say that the escape velocity is the one required to escape the earth's gravitational speed then we say the satellites stay in orbits because of the earth's gravitational speed how does that ha?
Satellites are traveling at less than escape velocity. (roughly, orbital velocity is about 7 tenths of escape).
What is anEscape Velocity?
Velocity sufficient for a body to escape from a gravitational attraction without acceleration. Earth has an escape velocity of 11.19 kmsec-1 .
What is the excape velocity on earth?
The escape velocity on Earth is approximately 11.2 kilometers per second (33 times the speed of sound). This is the speed required for an object to break free from Earth's gravitational pull and escape into space.
The escape velocity from Earth is greater for larger rockets than for small ones?
Escape velocity from Earth depends only on the mass of the Earth and the distance from its center, not the mass or size of the rocket. All rockets need to reach the same escape velocity to leave Earth's gravitational pull, regardless of their size.
What does the term 'escape velocity' mean?
Escape velocity is the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or moon. It allows an object to overcome gravity and travel into space without being pulled back. The specific escape velocity depends on the mass and radius of the celestial body.
The speed and direction a rocket must have to break away from a planet's gravitational pull?
The speed is called the escape velocity. An object travelling at the Earth's escape velocity will never return to Earth because as it moves away, and decelerates under the Earth's gravity, the force pulling it back (its weight) is also reducing and if it is above the escape velocity it will escape altogether.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
How fast must an object go to escape earth's gravittional pull?
An object must reach a velocity of about 25,000 miles per hour (40,000 kilometers per hour) to escape Earth's gravitational pull and enter into orbit around the sun. This speed is known as Earth's escape velocity.
How much speed required to go against gravity?
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.
Is the escape velocity higher for the earth or the moon?
The escape velocity is higher for Earth than for the Moon. Earth's escape velocity is approximately 11.2 km/s, while the Moon's escape velocity is about 2.4 km/s. This is because Earth is more massive and has a stronger gravitational pull compared to the Moon.
A rocket that moves upward from earth's surface at escape velocity will?
Escape the earth's gravitational pull and continue out into space. However, a rocket does not need to be launched at the escape velocity as it can continue to accelerate as it climbs. A gun projectile would need to be fired with the escape velocity. In a perfect system with only the projectile and the Earth: If the projectile is fired with the exact escape velocity it will travel to infinity away from the Earth. Upon reaching infinitely far away from Earth the projectile would have zero velocity. All of its kinetic energy (movement) would be transferred to potential energy.
Force required to break from Earths atmosphere?
The force required to break free from Earth's atmosphere and reach space is known as escape velocity. This velocity is approximately 11.2 kilometers per second (25,000 miles per hour) and varies depending on the location on Earth. It represents the minimum speed an object must have to break free from Earth's gravitational pull.
