What is speed? Explain.
Answers
Answer:
Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. ... An object with no movement at all has a zero speed.
Explanation:
Speed is the distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. Higher speed means an object is moving faster.
An example of speed is a car being driven 45 miles per hour. An example of speed is someone cleaning a room in 10 minutes.
The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.
