Subsonic
Instantaneous Speed.
The song "speed of sound" is sung by Coldplay.
The study of speed is called kinetics. It involves analyzing the motion of objects and the factors that affect their speed.
subsonic
Terminal velocity if it has reached its top speed. Or obviously constant speed.
Speed and direction is called velocity.
The speed is v and the starting speed is v0.
Subsonic speed refers to speeds below the speed of sound in a medium. In water, the speed of sound is higher than in air, so typical speeds of objects moving through water are considered subsonic.
The main difference is the speed of the object in relation to the speed of sound. Subsonic refers to speeds slower than the speed of sound, while supersonic refers to speeds faster than the speed of sound. In the case of supersonic speeds, objects are traveling faster than the speed at which sound waves propagate in the medium.
speeds lower than the speed of sound is known as the subsonic speed. speeds greater than the speed of sound is supersonic (mach 1) and speeds that are many times above the speed of sound (above mach 0) are known as hypersonic sounds.
Twice the speed of sound is called Mach 2. This means an object is traveling at twice the speed of sound, around 1,522 miles per hour at sea level.
