Question

Hola mates

what is escape velocity ?? write the expression of escape velocity.​

Answer 1

In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free object to escape from the gravitational influence of a massive body. ... Theescape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 36,700 ft/s; 25,020 mph; 21,744 kn) at the surface.

Escape Velocity, it's Formula and Derivation. ... So, escape velocity is defined as the minimum initial velocitythat will take a body away above the surface of a planet when it's projected vertically upwards. On throwing the object upwards, work has to be done against the gravity.
