Spring-loaded plungers use a spring and a plunger (or ball tip) to exert a precise and repeatable force. They are a better option than having engineers cobble together an assembly that uses a simple, ...

Dive into the physics of mass oscillation on a spring! This guide explains how to model spring force, including Hooke’s Law, oscillation frequency, and energy transfer, with clear examples to help you ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...
