What is escape speed?
Answers
Answer:
In physics, escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to achieve an infinite distance from it. Escape velocity is a function of the mass of the body and distance to the center of mass of the body.
Answer: The escape speed can also be said as the minimum speed required from an object to escape by the gravitational force produced from the bigger object. The unit of escape speed is a meter per second. as the mass of an object increase the gravitational force also increases. so the escape velocity should also be larger.
Explanation:
All the objects thrown up will fall down due to gravitational force but when a object never comes back and escapes the gravitational field it is said to be escape speed or escape velocity.
To launch a satellite in space it should escape the earth's escape velocity. the escape velocity of earth is considered to be 11.2 km per second.
The escape velocity of moon is 2.38 km per second, on considering moon is smaller than the earth so the escape velocity of the moon is much lower than the earth.
