Smaller, because Mars is less massive and less dense than Earth.

Well, Jupiter is a bigger planet so it has more mass and mass causes gravitational attraction which is a big factor in deciding your weight. Weight=Mass x Acceleration of gravity so the bigger the gravity the bigger your weight so you would weigh more on Jupiter because of its bigger acceleration due to gravity. Your mass is going to stay the same no matter what but the gravity will change.

That means that the acceleration of an object is caused by the force of gravity acting on the object.

Smaller. Something as big as the Earth would have so much gravity that it would probably have collided with something else and been eliminated

It would be smaller. The force on the particles will be the same. However, their bigger mass (inertia) will mean that their sideways acceleration is less than for lighter particles. They travel in a larger arc

IF gravity doubled, THEN your weight would double. And acceleration and the force of gravity are indistinguishable from each other.

I think it would be the acceleration of gravity 9.81 m/s^2...

The force between the two objects would INCREASE, the smaller object drawn to the object with bigger mass, but at the same time that bigger object would still be drawn to the smaller object.

The acceleration due to gravity is 9.81 meters per second. Since Force = Mass x Acceleration, the force of gravity would be the mass times 9.81.

If you are asking the rate of acceleration on a surface, than the larger the force of gravity is, the more it will affect the rate of acceleration. The amount of friction depends one many variables, one of which is gravity. The larger your force of gravity is, the larger the force of friction is. Because of this, the more the force of gravity is, than the slower the rate of acceleration is because of the larger force of friction, which would be acting against the rate of acceleration. Therefore, the force of gravity does affect the rate of acceleration.

No. Mass is a measure of the amount of "stuff" or matter a thing has. You wouldn't be smaller or bigger on the moon. You would, however, weigh less because weight is a function of gravity nand there is little gravity on the moon.

1. what value is assigned to the acceleration due to gravity on earth? The acceleration of gravity on earth is 9.8 meters per second per second. 9.8m/s2 2. what is the initial velocity of an object that is dropped? That would be Vi=0.

Acceleration depends on the mass: a=F/m. Unless it is acceleration due to gravity, where it would be constant no matter the mass.

You would feel heavier. The acceleration due to gravity on Uranus is 10.72, while the acceleration due to gravity of Earth is 9.8 m/s2 (or 9.81, it depends on who you ask.).

Not for sure but it seems like there would be more gravity at the equator than at the poles. The earth rotates and creates a centrifugal acceleration at the equator the counters the force of gravity. acceleration due to gravity =GM/R2 acceleration due to rotation =V2/R So gravity at the equator is GM/R2 - V2/R

To some extent, the crushing of rock at the earth's center would cause compression of the earth's 'underpinnings' and, it would get slightly smaller. Additionally, now being closer to the main Mass of the Earth would slightly increase the pull of gravity (Acceleration due to Gravity) seen on the earth's surface.

It would depend on what force is driving the acceleration. If that force is gravity, then acceleration is constant irrespective of variations in mass. All else being equal and presuming the acceleration is by the same exerted force on both the larger and smaller object, the larger object would experience 1/3 the acceleration. (The formula for determining the force is F = ma , the mass times the acceleration. For the same F, and m2 is 3m, then a2 must equal a/3. )

I depends about the amount of force applied, so larger objects require a larger amount of force to accelerate as much as a smaller would without the greater force applied.

In our Solar System you would weigh the most on Jupiter. [See related link] On whatever planet weighs the most or has the most mass. For example the acceleration due to gravity is 9.8m/s on earth. On lets say the moon, it has a smaller mass therefore has a smaller acceleration due to gravity. So you would "weigh" less. On Jupiter , because weight of 110 LB (50 kg) on Earth will be 276.5 LB(125.5 kg) on the planet Jupiter.

The mass of the sun is many times that of the earth, the result is that the acceleration of gravity is also much greater. Since the acceleration of gravity on the sun is higher, and the weight of an object is based on its mass and acceleration of gravity, the object would weigh considerably more

Since the force of gravity is directly proportional to mass, then increasing the mass of an object increases the force of gravity it produces.Since accceleration = force/mass, then increasing the mass of an object means it will have a smaller acceleration for the same force (or alternatively that you need more force to produce the same acceleration).

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.

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.
