The answer is simple. A force is a push or pull on something. If there is no something, then there is nothing to push or pull. So right off there must be at least the one object...the something that gets pushed or pulled.
But now we get to...what's doing the pushing or pulling? And there we have a requirement for that second object. And that's why there is that "interaction."
There has to be a pusher/puller and it has to push/pull something. There're the two objects.
EX: If you push out ahead with your hands, the first object, you exert no force with that push because there is no second object. But if you do that same push but up against the wall of your office, you exert a force onto that wall, which is the second object.
What else can I help you with?
Define interaction force and interaction distance?
Interaction force is the force acting between two objects as a result of their interaction, such as gravitational, electromagnetic, or nuclear forces. Interaction distance is the distance between the centers of mass of the interacting objects at which the interaction force becomes significant enough to influence their behavior.
What is the force between two moving called?
The force between two moving objects is called the force of interaction or the force of interaction between two objects. This force can be attractive or repulsive, depending on the nature of the objects and their velocities.
What type of forces must have contact to act on an object?
Contact forces, such as frictional force, normal force, tension force, and applied force, require physical contact between objects to act on the object. These forces result from direct interaction between the surfaces of objects in contact.
Why is magnetic force a non contact force?
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.
When is the gravitational force zero?
When you don't have gravitational interaction between objects.
Why is gravity a non contact force?
That means that it acts at a distance.
When an object exerts a force on another object the objects are?
When an object exerts a force on another object, the objects are interacting with each other through a force. This interaction can result in a change in the motion or deformation of the objects involved.
When does a force happen?
A force occurs whenever there is an interaction between two objects that causes a change in the motion or shape of one or both objects. This interaction can be contact forces, such as pushing or pulling, or non-contact forces, such as gravitational or magnetic forces.
What is a force between two charged object ( not touching ) called?
It is called an electric force. This force is caused by the interaction of the electric charges of the objects.
Does electric force require that objects touch?
No, electric force does not require objects to touch in order to act on each other. Objects with electric charge can exert attractive or repulsive forces on each other even when they are not in physical contact.
Two forces that don't depend upon physical contact?
Gravitational force and magnetic force are two examples of forces that do not require physical contact between objects to act on each other. Gravitational force is the attraction between masses, while magnetic force is the interaction between magnetic fields.
Is magnetic force an example of contact force?
No, magnetic force is a non-contact force that acts at a distance between objects with magnetic properties. It does not require direct contact between the objects to exert a force.
