The escape velocity from the earth gravitational field depend upon
Correct answer: D. Mass of Earth
- A. Rotation of earth
- B. Mass of body
- C. Radius of body
- D. Mass of Earth
Explanation
The escape velocity from a celestial body, such as Earth, depends on the mass of the body. A higher mass requires a higher escape velocity to overcome the gravitational pull.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
