专业提示

Velocity vs speed: speed is scalar (always positive), velocity is vector (can be negative). If you drive 100 km north then 100 km south, speed = 200 km but displacement = 0 and average velocity = 0.

难度:初级

你知道吗?

The fastest human-made object is the Parker Solar Probe, which reached 635,000 km/h (0.064% the speed of light) in 2023. By comparison, the International Space Station orbits at 27,600 km/h, and a rifle bullet travels at ~3,600 km/h.
