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?
The force of gravity decreases as the distance between the rocket and the planet increases. This relationship is described by the inverse square law, which states that the force of gravity is inversely proportional to the square of the distance between two objects.
Earths magnetic field is not the cause of gravity?
Correct, Earth's magnetic field is caused by the movement of liquid iron in its outer core, while gravity is a fundamental force that exists between all objects with mass. Gravity is the force that attracts objects towards each other, while the magnetic field is a result of the flow of charged particles in the core.
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.
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.
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?
I am not bound to Earth by electric forces, but rather by gravity. Gravity is the force that keeps me on Earth and prevents me from floating off into space.
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 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.
Why do the astronauts feel smaller gravity forces on the moon than on earth?
Astronauts feel smaller gravity forces on the moon than on Earth because the moon has less mass and therefore weaker gravity. The force of gravity is directly related to an object's mass, so the moon's lower mass results in weaker gravitational pull on its surface compared to Earth.
Is the gravity on mars smaller or larger then earth?
Gravity on Mars is substantially lower than on Earth.
