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 objects are similar because they are both areas where forces can act without objects touching?
Two examples of objects that are similar in that forces can act without objects touching are magnets and electric fields. In both cases, forces can act at a distance without direct contact between the objects.
The total momentum of a group of objects is conserved unless?
b. outside forces act on the objects.
What objects do forces act on?
Forces act on all objects with mass. This includes everyday objects like books, cars, and furniture, as well as celestial objects like planets and stars. Forces can cause objects to move, accelerate, deform, or rotate.
Why does and object move if the action reaction forces are equal?
An object can still move even if the action and reaction forces are equal because they act on different objects. The equal forces produce opposite accelerations on the two objects, causing them to move in opposite directions. This is described by Newton's third law of motion.

What is it called when two or more equal forces act on an object?
falling objects.

b. outside forces act on the objects.
In newtons third law the action and reaction forces?
The two forces are of the same magnitude, act in opposite directions, and act on different objects.

Are there two different types of external force?
External forces can generally be classified into two categories: contact forces, which act through direct physical contact between objects (such as friction or tension), and non-contact forces, which act over a distance without physical contact (such as gravity or electromagnetic forces). Both types of forces can influence the motion or interactions of objects.
How do matches forces act on objects?
If they are balanced and equal they have no overall effect on the acceleration of an object.
What is the meaning of contact forces?
Contact forces are forces that act between two objects that are physically touching. These forces can include friction, normal force, tension, and applied force. They are a result of direct interaction between the surfaces of the objects in contact.
What are two ways that forces can act?
Forces can act through contact, where objects physically push or pull against each other, such as a person pushing a box. They can also act at a distance, where the objects do not need to make direct contact, such as gravitational attraction between the Earth and an object.
What forces that act on objects without touching them?
Some forces that act on objects without touching them include gravitational force, magnetic force, and electric force. These forces can exert a push or pull on objects even when they are not in direct contact with them.
