Gravity

USUK
US/ˈgrævɪti/

The fundamental force of attraction between objects with mass.

Also: gravitation

Definition

Gravity is one of the four fundamental forces of nature, responsible for the attractive force between any two objects that have mass. Newton described it with his law of universal gravitation, while Einstein's general relativity explains gravity as the curvature of spacetime caused by mass and energy. Gravity governs the motion of planets, stars, and galaxies.

Example

The Moon stays in orbit around Earth because Earth's gravitational pull continuously curves the Moon's path, preventing it from flying off into space in a straight line.

Usage Examples

  1. 1

    The team applied gravity best practices to improve their physics outcomes significantly.

  2. 2

    Understanding gravity is essential for anyone building a career in STEM.

When & How to Use

Use 'Gravity' when working in Physics contexts where gravity is one of the four fundamental forces of nature, responsible for the attractive force between any two objects that have mass.

  • Applying gravity principles during a physics project or initiative
  • Explaining gravity to a junior team member or stakeholder unfamiliar with STEM
  • Evaluating options or proposals using gravity as a decision-making criterion

Etymology & Origin

The term 'Gravity' derives from professional usage and entered STEM professional usage as the field formalised in the 20th century.

History & Evolution

The concept of gravity has evolved alongside STEM. Early practitioners relied on informal methods; structured approaches emerged with the professionalisation of physics in the mid-20th century. Today, gravity is a standard part of STEM practice globally.
