In this video, we model a catenary curve using a mass-spring system, showing how a chain-like shape can emerge from discrete masses connected by springs. We connect the simulation to real physics, ...

Jump start physics problem with a mass on a spring. This video explains the setup, key assumptions, and the step-by-step physics needed to solve for motion, energy, and forces in a spring–mass system.

A research team affiliated with UNIST has reported a new simulation tool to better understand how liquid-phase chemical warfare agents (CWAs) disperse and persist in urban environments. Their findings ...

DUBAI - Dubai Electricity and Water Authority (DEWA) has been granted a UAE patent for a Feeder Input-Output Simulator for Substation Automation Applications. This achievement reflects its commitment ...

For years, black wrap has protected the edges of Springfield’s Campanile, where long cracks mar Indiana limestone. Its bells hang silent and the hands of its four-sided clock sit frozen in time. The ...

Abstract: Existing real-time simulation methods for cascaded power electronic systems face significant challenges. Physics-driven approaches often suffer from limited applicability when critical ...

Abstract: This paper presents a simulation-based benchmarking analysis of three reinforcement learning (RL) algorithms—Soft Actor-Critic (SAC), Deep Q-Network (DQN), and Proximal Policy Optimization ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Gordon Scott has been an active investor and ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...

Journalist Karen Hao unpacks the rise of AI “empires,” their ideological roots, and the hidden environmental and societal costs of OpenAI’s quest for artificial general intelligence.
