ā 13y agoIf the planet is smaller, then it can't have the same size.
If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller.
If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.

ā 13y agoNo, the gravitational force experienced on the surface of a planet is determined by both its mass and radius. A smaller planet with the same shape and size as Earth would have less mass, which would result in weaker gravity compared to Earth.
The gravity on Venus would be about 90.4% of Earth's (0.904 g). Although the planet has a smaller mass, it also has a slightly smaller diameter.
Venus has lower gravity than Earth because it has a smaller mass than Earth. Gravity is directly proportional to the mass of a planet, so planets with smaller masses will have lower gravitational forces.

The acceleration due to gravity on Mercury is approximately 3.7 m/sĀ², which is about 38% of the acceleration due to gravity on Earth. This is due to Mercury's smaller mass and radius compared to Earth.
Venus has a surface gravity of 8.87 m/sec2 or 0.904 g.For comparison the Earth has a gravity of 9.780327 m/s² or 0.99732 gSo the gravity on Venus would be about 90.4% of Earth's. Although the planet has a smaller mass, it also has a slightly smaller diameter.
Mars has a weaker gravity than earth because it is a smaller planet and is smaller than
If Earth became much smaller, the force of gravity on its surface would decrease because gravitational force is directly proportional to the mass of the planet. The smaller size would also result in less gravitational attraction between objects on Earth and a weaker gravitational pull overall.

Depends on how much smaller my planet was. If my Earth were too small to create enough gravity to hold an atmosphere or an ocean, I would not be here -- indeed, no life would be here -- to get upset over too small a planet. I'm sure it's the same situation on your planet.
Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
You already stated in the question that it has 3.4 times the gravity of Earth.

YES! the size of the planet does effect your throwing ability! If you get each planets' gravity number then you will notice that the smaller the planet the less gravity force/attraction it will have. If you go to Jupiter and throw a football the gravity will pull down on the football faster and make your throw much shorter than it would on Earth because Jupiter has a bigger gravity number then Earth.
Planets with a smaller surfae gravity than Earth are Mercury, Venus, Mars, and Uranus.
Assuming the planet was just like Earth in every other way... First, the planet would have to be large enough to have enough gravity to sustain an atmosphere, or it would be impossible for a human to survive. As long as the planet had enough atmospheric pressure, then a human could survive, but their bones would slowly degenerate because when there is someone is not subjected to enough gravity, the bones become weaker.

Well you would need to know the force of Gravity on the surface of Planet A to answer this. The equation to use would be 5 multiplied by the force of gravity on Planet A = the weight in kilograms. So if Gravity on planet A was twice that on Earth then it would weigh 10Kg and if it was 1/2 that on Earth it would weigh 2.5 kg.
