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.

What can forces change the movement of objects?
Forces such as gravity, friction, and applied forces can change the movement of objects. Gravity attracts objects towards the Earth, friction opposes motion between surfaces, and applied forces like pushing or pulling can accelerate, decelerate, or change the direction of an object's movement.
How does the force of gravity pulling on the rocket change as the distance between it and the planet increases?
Gravity doesn't change, no matter where you are. One of the characteristics of the forces due to gravity is that they're inversely proportional to the square of the distance between the two masses involved. So as your distance from a planet changes, the mutual forces attracting you and the planet toward each other change in inverse proportion to the square of the distance between you and the center of the planet.
Earths magnetic field is not the cause of gravity?
No. Those are two quite different forces. The Earth's gravity is caused by the amount of mass Earth has.No. Those are two quite different forces. The Earth's gravity is caused by the amount of mass Earth has.No. Those are two quite different forces. The Earth's gravity is caused by the amount of mass Earth has.No. Those are two quite different forces. The Earth's gravity is caused by the amount of mass Earth has.
What three forces cause an object to change its motion?
The three forces that cause an object to change its motion are gravity, friction, and applied forces. Gravity pulls objects towards the center of the Earth, friction opposes motion between surfaces, and applied forces are those exerted by external agents to push or pull objects in a certain direction.
What are the three natural forces of the earth?
The three natural forces of the Earth are gravity, electromagnetism, and nuclear forces. Gravity is responsible for pulling objects toward the Earth, electromagnetism governs interactions between charged particles, and nuclear forces hold particles within atoms together.
Why does venus have lower gravity than earth?
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.
Which force pulls everything down to earth?
The force that pushes downward on objects on earth is called gravity.
What are the 2 forces that change the surface of the Earth?
The two forces that change the surface of the Earth are weathering, which breaks down rocks into smaller pieces, and erosion, which transports these rock fragments to different locations.
What can forces change the movement of objects?
Forces such as gravity, friction, and applied forces can change the movement of objects. Gravity attracts objects towards the Earth, friction opposes motion between surfaces, and applied forces like pushing or pulling can accelerate, decelerate, or change the direction of an object's movement.
What causes the earth to have gravity?
Earth is hafly big, so it has gravity. Larger, it has more gravity. Smaller, it has less gravity.
Are you bound to earth by electric forces or by gravity?
gravity because gravity is dependant on mass and not on charge like an electric field
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
Does gravity change as we move away from the earth?
No. Gravity always behaves according to the same formula, introduced by Newton.But the gravitational forces between you and the Earth certainly change when thedistance between you and the Earth's center changes significantly.
Does mars have smaller gravity than earth greater gravity than earth or the same gravity as earth?
Mars has approximately one third the surface gravity of the earth
Does mercury have a smaller or larger gravity then earth?
Much smaller.
Is the gravity on mars smaller or larger then earth?
Gravity on Mars is substantially lower than on Earth.
Why do the astronauts feel smaller gravity forces on the moon than on earth?
The actual force of Gravity caused by an object is defined mostly by its mass-density.The moon possesses a mass many times less than the mass of earth.The gravital force exerted by the moon is about 1/6th that of the earth's.
