are force and area directly proportional?

Pressure depends on the amount of force and the area over which the force is applied. More force - more pressure. More area - less pressure. In fact, pressure is directly proportional to force, and inversely proportional to area.

then a stronger relationship emerges: the area is proportional to the square of the perimeter, where the constant of proportionality depends on the shape you chose. For example, a square of perimeter has area , while a circle of perimeter has area .

Per my graph the relationship between the force and the current is adirect/proportional relationship. When one increases so does the other andvice versa.

If you mean can the magnitude (the size) of a force be negative then the answer is no. There is no meaning to the idea of a force value less than zero force. HOWEVER: Force is a vector. If you define a positive DIRECTION for force then a negative force is simply in the opposite direction.

A: Newton's second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor.

Newton's law states: The gravitational attraction force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation distance. The force is always attractive and acts along the line joining them.

The acceleration is directly proportional to the net force; the net force equals mass times acceleration; the acceleration in the same direction as the net force; an acceleration is produced by a net force.

The magnitude of the force required to change the length of a spring-like object is directly proportional to the spring constant and the displacement of the spring. Elastic potential energy is directly proportional to the square of the change in length and the spring constant.

The gravitational force between two objects is proportional to their masses and inversely proportional to the square of the distance between their centers.

The ratio of electrostatic force & gravitational force is 10^38:1. The significance of gravitational Forces in case of a pair of charges is almost negligible. Usually, this ratio is helpful in study of nucleus & the Forces existing between them (nuclear forces).

Force and Surface Area. When a force is applied perpendicular to a surface area, it exerts pressure on that surface equal to the ratio of F to A, where F is the force and A the surface area. Hence, the formula for pressure ( p ) is p = F / A.

They are not related either directly or inversely unless the radius is held constant. The period of an object () can be calculated where is the speed. So, if radius and mass are held constant, centripetal force is inversely related to the square of the period.

The acceleration of an object is parallel and directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.

If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

Electrostatic force and distance are inversely related. The pattern between electrostatic force and distance can be further characterized as an inverse square relationship.

In science, a force is a push or a pull. All forces have two properties: direction and magnitude. A newton (N) is the unit used to describe the magnitude, or size, of a force.

Momentum is mass times velocity. So force is the change in (mass times velocity) with respect to time: F = d(mv)/dt. In most situations we figure mass is constant. So force is proportional to a change in velocity.
