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.
it pulls the object towards the earth which kind of slows it down i guess. or is that friction? For an object travelling in the Earths atmosphere, or near to the Earth above the atmosphere, gravity provides a force pulling the object towards the centre of the Earth. Unless the object is travelling fast enough, what is called the escape velocity, this gravity force will ultimately cause the object to fall back to the surface. Friction is something else, the friction with the air in the atmosphere also slows the object, but this force acts in opposition to the direction of motion, not towards the Earths centre. To compute the trajectory of the object you need to take both forces into account.
Yes, a slow object can travel as far as a fast object given enough time. The distance traveled depends on the speed of the object and the duration of its travel.
Velocity.
An object's speed in a given direction is its velocity. Velocity is a vector quantity that includes both speed and direction. It describes how fast and in which direction an object is moving.
The object's motion is described by its velocity, which includes both speed and direction. The speed tells us how fast the object is moving, while the direction indicates the path it is following.
An object has to travel in a speed of 25km per second.
It must go atleast 11.2 km/s on earth :)
In order to escape the gravity of a black hole, an object would have to travel faster than the speed of light - something that is impossible.
As fast as your fingernails grow
To escape the Earths gravity the shuttle goes 17,500 miles an hour. You can use that value to figure out how far it goes in 500 seconds.

It isn't clear what exactly you mean with "escape gravity". The effects of Earth's gravity (for example) extend all the way to infinity, while getting weaker and weaker at a greater distance. So in a way, an object moving away from Earth never "escapes gravity". If an object moves fast enough - about 11.2 km/second near Earth's surface - it is said to have reached "escape velocity", in this case, it is fast enough never to come back. A rocket will reach escape velocity in a few minutes.
to escape from its predator so it need to swim very fast to escape from them or to swim fast to catch preys :-)
Yes It does break your fast for a short answer.
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.
Like I know that.....
