Trains travel at different speeds. Passenger trains on shared tracks with freight trains usually run at a maximum speed of 79 mph. On dedicated tracks, they can reach 90 mph or more. Diesel-powered passenger trains can achieve speeds up to 125 mph, depending on track conditions and separation from freight trains. In the U.S., Amtrak’s … Read more
Tornados typically move at speeds between 10 and 20 miles per hour. However, some can exceed 60 miles per hour. Their ground time varies, lasting from a few minutes to over an hour. Statistics on the occurrence and specific wind speeds during these events can differ widely based on conditions. Safety during a tornado event … Read more
Tornadoes can move at speeds from less than 1 mph to over 60 mph. Their typical travel speed is 10 to 20 mph. The time tornadoes spend on the ground varies. Some tornadoes may stay down for only a short time, while others can last longer. Statistics on the duration and occurrence of tornadoes are … Read more
Modern submarines travel faster than 30 knots (about 35 miles per hour) underwater. Their travel speed varies based on design and propulsion systems. Information about American naval vessels is mostly classified. Continuous advancements improve their speed and maintain information confidentiality while enhancing stealth capabilities. Records for underwater speeds highlight the capabilities of these vessels. The … Read more
Stars in the Milky Way usually travel at speeds of about 100 km/s. However, hypervelocity stars can move at speeds close to 1000 km/s. These fast stars mainly form in locations near the center of the Milky Way, where star density is higher than in the galaxy’s outer regions. Factors such as a star’s mass … Read more
NASA’s fastest spacecraft, the Parker Solar Probe, reaches about 700,000 kilometers per hour. This speed is much slower than the speed of light, which travels at approximately 1,080,000 kilometers per hour. Spacecraft speeds differ based on mission goals and technological advancements. Other notable spacecraft include Voyager 1 and New Horizons. Current spacecraft technology includes rockets … Read more
Space shuttles travel at speeds of about 27,358 kilometers per hour (17,000 mph) to reach orbit. After jettisoning the solid rockets, the main engines continue to provide thrust for acceleration. This phase lasts roughly six minutes and produces a combined thrust of over 1.2 million pounds. During reentry, the situation changes drastically. Space shuttles travel … Read more
Solar flares eject plasma that travels at speeds between 43,200 mph and 4 million mph (20 to 20,000 km/s). The typical speed is around 1 million mph (about 450,000 km/s). This fast movement influences space weather conditions significantly. The effects of solar flares on space weather can include disruptions to satellite communications, navigation systems, and … Read more
An average sneeze travels up to 100 mph. It projects droplets that can carry thousands of germs. These droplets can reach several feet away. Sneezes pose a health risk by spreading illness-causing germs to people nearby, contributing to the transmission of diseases. Germ transmission risks associated with sneezes are significant. When a person sneezes, they … Read more
Snails travel at a speed of about 0.03 miles per hour (1.3 centimeters per second). They can cover roughly 150 feet in an hour. Some species move faster, reaching a maximum speed of 0.047 kilometers per hour (0.029 miles per hour). This crawling behavior illustrates their efficiency in moving across surfaces. Snails also demonstrate interesting … Read more
