Spring Force

Spring force is a type of force exerted by a spring when it is stretched or compressed. It is a restoring force that causes the spring to return to its equilibrium position.

Factors Affecting Spring Force

The magnitude of the spring force depends on two main factors:

1. Spring Constant (k): The stiffness of the spring, measured in units of force per unit of length (e.g., N/m or lb/in).
2. Displacement (x): The distance the spring is stretched or compressed from its equilibrium position.

Hooke's Law

Hooke's Law describes the relationship between the force exerted by a spring and its displacement:

F = -kx

Where:

• F is the spring force in newtons (N) or pounds (lb).
• k is the spring constant.
• x is the displacement from the equilibrium position.

Calculating Spring Force

The formula to calculate spring force is:

F = kx
