Frequently Asked Questions
Q. What is the SI unit of speed?
The SI unit of speed is meters per second (m/s).
Q. How do you calculate speed?
Speed is calculated using the formula: distance divided by time.
Q. What is the difference between speed and velocity?
Speed measures only magnitude, while velocity includes both magnitude and direction.
Q. How many km/h is 1 m/s?
1 meter per second is equal to 3.6 kilometers per hour.
