In physics, escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body. The escape velocity from earth is about 40,270 km/h (25,020 mph).
The first scientist to measure speed as distance over time was Galileo. A speedometer is a great example of instantaneous speed. The speed of light can also be written as 186,282 miles per second. The speed of sound in dry air is 343.2 meters per second. The escape velocity of Earth is the speed needed to escape from Earth's gravitational pull. It is 25,000 miles per hour.
