What are the two categories of forces?
The two categories of forces are contact forces, which occur when two objects are physically touching, and non-contact forces, which act between objects that are not in direct physical contact.
What two forces keep the universe moving and attracts objects toward each other?
Gravity and inertia are two forces that keep the universe moving and attract objects toward each other. Gravity pulls objects together due to their mass, while inertia is the tendency of objects to maintain their state of motion. Together, these forces help govern the motion of celestial bodies in the universe.
Do all objects have two forces acting on them at all times?
No, all objects do not necessarily have two forces acting on them at all times. Objects can have multiple forces acting on them simultaneously, or just one force, depending on the situation.
What occurs between any two objects?
The interaction between two objects can involve forces such as gravity, electromagnetism, or contact forces. These forces can cause objects to attract, repel, or cause motion between them. The specific interactions depend on the properties of the objects and the distance between them.
What determines the strength of an electric force between two objects?
The strength of an electric force between two objects is determined by the magnitude of the charges on the objects and the distance between them. The greater the charges and the closer the objects, the stronger the electric force will be. Additionally, the medium surrounding the objects can also affect the strength of the electric force.

What determines the strength of the force between two objects?
-- The product of the net charges on the two objects, the distance between their centers of net charge, and the nature of the material in the space between them, determine the magnitude of the electrostatic forces between them. -- The forces act along the line between the centers. Whether the forces point toward each other or away from each other depends on whether the net charges on the two objects have the same or opposite signs.
What are the similarities between contact and non contact forces?
A contact force, including friction, springs, pushes, pulls, requires the two objects to be in contact for the force to exist. On the other hand, non-contact forces do not require contact; the two objects are separated by space, and yet the force exists. This includes gravity, electricity, magnetism, and nuclear forces.

What determines the strength of the forces of gravity between two objects?
The product of the masses of the two objects, and the distance between them.
The area separating two objects?
SPACE
What are the differences between plane forces and space forces?
In plane forces, all forces are confined to a two-dimensional plane, while in space forces, forces can act in three dimensions. Plane forces involve only forces in the x and y axes, while space forces can include forces in the z axis as well. Space forces require vector analysis in three dimensions, while plane forces use scalar analysis in two dimensions.

The strength of an electric force between two objects is determined by the magnitude of the charges on the objects and the distance between them. The greater the charges and the closer the objects, the stronger the electric force will be. Additionally, the medium surrounding the objects can also affect the strength of the electric force.
How can astronomers tell how much objects in space weigh?
Weight is due to gravitational forces between two objects. A single object inspace without another one reasonably nearby, or even in gravitational free-falltoward another object, is weightless. So you can not weigh an object in space.Determining the mass of objects in space is another matter.
What are forces in which two interacting objects are physically in contact with each other?
Contact forces include friction, normal force, tension, and applied force. These forces arise when two objects are touching and directly exerting a force on each other.
