Is escape velocity and escape speed …

The correct term is ‘escape speed’. While others argue that you must be traveling in a certain direction in order to escape the gravitational pull of the primary, they neglect to say that the term ‘escape velocity’ is almost never used along with a direction in which the object is moving. If you want to use the term ‘velocity’, then you must give a direction. If you don’t, then you are simply adding to the obfuscation that already exists between these terms. On a moon or another body with negligible atmosphere, you can move in almost any direction you like at the escape speed and still escape the body’s gravity. The only requirement on your direction is that you don’t end up hitting the body itself. It is not the velocity that is limiting you; it is the speed. These two words are so conflated in popular culture already; it’s time to de-conflate them.

But Priya Dharshini, you have described Escape velocity...what about escape speed?

If I m wrong then correct me

I think they both are same....bcoz speed also depends on magnitude ....and escape velocity also says that at what magnitude we throw anything so it goes outside the earth field ...

Escape velocity is the minimum vertical speed required to over come the gravitational pull of the Earth and to leave its orbit. Escape velocity for the Earth is relatively constant and is approximately 7 miles/s.
