When a stone is brought from the surface of the moon to the Earth, its mass will remain the same, as mass is an intrinsic property unaffected by gravitational fields. However, its weight will change due to Earth’s stronger gravity, ...
If a body is thrown from the Earth with a velocity of 11.2 km per second, then the body will never return to the Earth. This velocity exceeds the escape velocity of Earth, ensuring that the body will continue moving ...
The period of a Geostationary Satellite is 24 hours. A geostationary satellite orbits the Earth at the same rate as the Earth’s rotation, completing one orbit in 24 hours. This allows it to appear stationary relative to a fixed point ...
With 11.2 km/s minimum velocity will a rocket overcome the Earth’s gravity and go into space when launched from the Earth’s surface. This velocity is known as the escape velocity, the minimum speed required for an object to break free ...
