⚡ SPEED — From Cheetahs to Light: The Physics of Motion and the Limits of Nature
1. What Is Speed? Speed is one of the simplest yet most profound concepts in physics.It measures how fast an object moves — or in scientific terms, the distance covered per unit of time. Speed=DistanceTime\text{Speed} = \frac{\text{Distance}}{\text{Time}}Speed=TimeDistance Speed tells us not only how quickly something changes its position but also forms the foundation for understanding […]
