Speed is the rate at which an object moves or travels over a specified distance. It tells us how fast something is changing position, whether it's a car on a highway or light traveling through space. Speed can be measured in various units like kilometers per hour or meters per second, giving us a detailed view of how quickly things move around us.
- Meter per second: A scientific measurement of speed, representing how many meters are covered per second.
- Kilometer per hour: Often used for road speeds; for example, 1 meter per second is equivalent to 3.6 kilometers per hour.
- Miles per hour: Common in the US for speed limits and vehicle speeds; 1 mile per hour equals approximately 1.609 kilometers per hour.
- Foot per second: A unit of speed, commonly used in physics and engineering, representing the number of feet covered per second.
