What is speed?

What is speed?. Speed is a measure of how far an object moves in a given time. . This car is travelling at 60 mph. This means the car travels 60 miles every hour. This jet is travelling at 350 m/s. This means the jet travels 350 metres every second. How is velocity different to speed?.

MOTION

MOTION. Chapter 11. How do you know something is moving?. Depends on your frame of reference. A frame of reference is the location from which motion is observed. Most common: the earth. Measuring distance. Distance: the length of a path between two points.
