Gravity is not a 'wave', it is a field of curvature of space-time caused by objects with mass. A black hole contains the mass of a star, compressed to the space of a single atom (a singularity), the compression of so much mass into such a small space, is why the black hole has such a powerful gravitational pull.
What else can I help you with?
Why you must study escape velocity?
You don't. "Escape velocity" is a meaningless number. "Escape velocity" is the speed at which a CANNON SHELL must be fired in order to escape from the Earth's gravity well. With a powered rocket, you can "escape" from the Earth's gravity at ANY speed - as long as you have enough fuel.
The speed and direction a rocket must travel to break away from a planet's gravitational pull is called?
To escape the gravitation pull of an object you must travel at or in excess of the escape velocity. The direction of the escape velocity is always radially outward from the center of the object.
How does gravity escape a black hole?
Gravity is a force acting on masses. It doesn't escape, since it directly alters spacetime; it doesn't travel along it.
What is the escape velocity of planet Jupiter in miles per hour?
The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.
How many miles an object take to escape from earths gravitational pull?
To fully escape Earth's gravitational pull, an object would need to reach a speed of about 25,000 mph or approximately 40,000 km/h. This is known as the escape velocity and is the minimum speed required for an object to break free from Earth's gravity. The distance an object would need to travel to achieve this speed would depend on various factors such as altitude, initial velocity, and atmospheric conditions.
How is a rocket able to escape earth's gravity?
It can never escape it entirely. It can, however, travel fast enough that the increasing distance outweighs the effect of the decreasing gravity. On earth, this velocity is about seven miles per second.
Why does a space shuttle have to travel so fast?
Space shuttles must travel at 11km/s so that they can escape the force of gravity. the force of gravity is approximately 9.81. If you don't travel at a greater speed than the force of gravity, the rocket will not launch.
What will a rocket do if it reaches escape velocity?
If a rocket reaches escape velocity, it will be able to break free from a celestial body's gravitational pull and travel into space indefinitely without falling back to the surface. This velocity ensures that the rocket's kinetic energy is greater than the potential energy at that altitude, allowing it to overcome gravity's influence.
What is the speed of the earth to escape the sun's gravity?
The escape velocity from the Sun at the Earth's distance is about 42.1 km/s. This means that for an object to escape the Sun's gravity at this distance, it would need to travel at that speed. The Earth's orbital speed around the Sun is about 30 km/s, so it is not moving fast enough to escape the Sun's gravity.
Why you must study escape velocity?

A rocket will move upward as long as the thrust is greater than the force of gravity?
Actually for some time even after the thrust is no longer greater than gravity. When the rocket's thrust is greater than gravity, it will be accelerating (its velocity upwards will increase). When the rocket's thrust is no longer greater than gravity, at that moment it will still have an upward velocity, so it will still travel upwards - it will only travel more and more slowly upwards as gravity starts to sap the rocket's upward velocity towards zero. Once its velocity reaches zero, if gravity is still winning over the rocket's thrust (if any), then it will start to fall back towards the ground.We are assuming a simplistic model (no air resistance, no super-unlucky collisions with meteors, etc.), but this is the basic idea.
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.
What would happen if the projectile were thrown with greater velocity?
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.
What would happen if a projectile were thrown with greater velocity?
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.
Why cant a spacecraft go beyond earths gravity?
The Earth's gravity is indefinite. The earth will always present a force on a spacecraft, no matter the distance. However, the force could become very very small with increased distance.A space craft can go past the point where earth's gravity will not cause them to fall back to Earth. Some crafts stay in orbit, so they are still close enough to the earth to stay "locked" into its gravitational pull, but other crafts such as the Titan have gone very far beyond.Any object with mass has an escape velocity. The escape velocity is the velocity at which an object must travel in order to escape the gravitational pull of the massive object. The escape velocity of the Earth is 11.186 kilometers per second (a little over 25,000 miles per hour). If an object can travel at that speed away from the Earth, it will travel away from the Earth and it won't be pulled back in.
The speed and direction a rocket must travel to break away from a planet's gravitational pull is called?
To escape the gravitation pull of an object you must travel at or in excess of the escape velocity. The direction of the escape velocity is always radially outward from the center of the object.
How fast must an object go to leave a planets gravity?
The speed that ab object must travel at to escape a planet's gravity is called escape velocity. This value varies depending on the mass and diameter of the planet. Here are the escape volcities of the eight planets of our solar system. Mercury: 9,400 mph Venus: 23,000 mph Earth: 25,000 mph Mars: 11,000 mph Jupiter: 133,000 mph Saturn: 77,000 mph Uranus: 48,000 mph Neptune: 53,000 mph Note that escape velocity only takes gravity into account and ignores other forces. An object launched from Earth's surface or from any other planet with a substantial atmosphere at escape velocity would be quickly destroyed and slowed down by air resistance.
