Answer 1

Escape speed (escape velocity), in simple terms is the minimum velocity required for an object to completely break free from the gravitational pull of another body. That, is the object projected must reach infinity, where it may stop (practically, it should not).
To calculate the escape velocity of a planet of mass M, and radius R, we equate the kinetic energy of the body in question to the potential energy while at the surface of the planet, since the energy at 'infinitt' must be zero (Potential energy+Kinetic energy)
And thus we get the following equation:
$\frac{1}{2}mv^2=\frac{GMm}{R}\\ \implies v^2= \frac{2GM}{R}\\ \implies v=\sqrt{\frac{2GM}{R}}$

Answer 2

Escape speed is the minimum speed with which a mass should be protected from the Earth's surface in order to escape Earth's gravitation field . Escape speed also known as , escape velocity is defined as :

| The minimum speed that is required for

| an object to free itself from the gravitational force

| exerted by a massive object .
