Because Venus and Earth are very similar in size, their gravity is almost the same. For example, if a 75kg person stepped onto Venus' surface, they would weigh 67.5kg.
The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass. F...
