Characteristics of non contact force

Answer 1

two objects that appy equal force to eachother. Such as when you balance two cards against each other. Neither card is applying greater force than the other, so they stand. If this were not the case, however, then the two cards would fall due to the unequal forces

Answer 2

Answer: The four main characteristics of force are

a)

Magnitude: The Quantity Of Force Is Known As Its Magnitude. The 'magnitude' of a force is its 'size' or 'strength', regardless of the direction in which it acts. For example, the force of a 5-pound weight in your hand, pushing down, has the same magnitude as a 5-pound pull on a rope, a 5-pound push on a wall, or a 5-pound force pushing up against the ceiling.

b)

Direction: The direction of a force depends on the direction the force is coming from, and will remain constant unless changed by some other force, etc.

c)

Point of application:The point where the force is applied is called Point Of Application.

d)

Line of action: Line of action of force is a line, passing through point of application of force and also contains the direction of force.

Answer 3

It means that the force acts at a distance, without a direct contact.
