what is the relationship between the force applied to a spring and the amount it stretches?

When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.

a = f (net) / m, where a = acceleration, f (net) = the net force acting on the object, m = the mass of the object.

The constant k is called the spring constant and is always a positive number. The minus sign in the above equation keeps track of the direction of the force, the force exerted by the spring is always opposite in direction to the direction the spring is stretched.

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass.

Linear Equations in Two Variables Force applied on a body is directly proportional to the acceleration produced in the body.

force = mass * acceleration. So inertia is proportional to mass and the relationship really comes down to the acceleration imparted on a mass by a force based on the above equation.

This is determined by the pitch with which the springs are wound. On sectional garage door springs, this normally is 15 percent. For example, a 100-pound pull spring requires 15 pounds of weight to separate the coils; when a door is open, the two springs will support 15 pounds of door weight without any stretch.

Acceleration is proportional to the applied force: The larger the force, the more an object will accelerate, in the direction of the applied force. Mass is inertia, i.e., reluctance to accelerate, so for the same force, more massive objects experience smaller acceleration than less massive ones.

A Newton meter is just any device that measures force (it's called a "Newton meter" because a "Newton" is a unit of force). A spring balance is a device that measures force by measuring how much a string stretches when a force is applied to it.

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.

Newton's 2nd law states that if a net force acts on an object, it will move at constant velocity. For a constant mass the acceleration of an object is directly proportional to the applied force. ... The momentum of an object remains the same unless an unbalanced force acts on it.

You can use a device called a force meter to measure the size of a force. Most force meters have a hook that you can use to hang or pull on something. This will cause a spring to move and show you how much force is being applied. We measure forces using a unit called Newtons.

If given a constant area the force applied is directly proportional to the pressure. If the force is held constant the pressure is inversely proportional to the area. If the area is doubled the pressure is halved. If the pressure is held constant then the force is directly proportional to the area.

If the force is constant, work may be computed by multiplying the length of the path by the component of the force acting along the path. To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd.

…the force is called the spring force. If x is positive (displacement to the right), the resulting force is negative (to the left), and vice versa. In other words, the spring force always acts so as to restore mass back toward its equilibrium position.

Spring Constant or force constant is defined as the applied force if the displacement in the spring is unity. It is denoted by k. The dimensional formula can be worked out by using the spring force formula i.e. F = kx . This gives k = F/x.

Forces can be measured using a force meter, also called a newton meter. Force meters contain a spring connected to a metal hook.
