Would a smaller planet than earth with the same shape and size have more gravity?

If 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.

What is the gravity on Venus 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.
What stops oxygen from leaving the planet?
The gravity of the Earth and to a smaller extent the Van Allan Belt.
What happen to the human gravity on Mars?
The planet Mars is smaller than Earth and has a weaker gravitational field. As a result, people on Mars would weigh less than they do on Earth.
Why would you weigh 57 pounds on Mars if you weigh 150 on Earth?
Your weight depends on the gravity, and Mars, being a smaller/lighter planet has less gravitational pull than the earth.
Would the gravity on the planet Mercury squash someone?
No. The gravity on Mercury is less than half that of Earth.
Is Mars' gravity stronger or weaker than earth's?
Mars has a weaker gravity than earth because it is a smaller planet and is smaller than
What is the gravity on Venus 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.
What if your planet was smaller?
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.
Is mercurys gravity stronger than earths?
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".
What would be the gravity in relatation to earth of a planet with 3.4 times the gravity on earth?
You already stated in the question that it has 3.4 times the gravity of Earth.
What stops oxygen from leaving the planet?
The gravity of the Earth and to a smaller extent the Van Allan Belt.
What happen to the human gravity on Mars?
The planet Mars is smaller than Earth and has a weaker gravitational field. As a result, people on Mars would weigh less than they do on Earth.
What planet Force of gravity is less then half of earths?
Planets with a smaller surfae gravity than Earth are Mercury, Venus, Mars, and Uranus.
Does the size of a planet effect your throwing ability?
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.
Why would you weigh 57 pounds on Mars if you weigh 150 on Earth?
Your weight depends on the gravity, and Mars, being a smaller/lighter planet has less gravitational pull than the earth.
How would humans react on a smaller planet than earth?
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.
How much would an object with a mass of 5 kg weigh on Planet A?
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.
