Relative speed is the speed between two moving objects with no regards to a fixed reference. Speed is how fast something is moving with respect to an object.
Mach refers to the speed of sound. A plane that travels at Mach 2 means that it travels twice the speed of sound in air. The actual speed will vary a bit depending on the altitude.Mach number is a measure of relative speed. It is the speed of something relative to a medium, usually air, and divided by the speed of sound in that medium: : : is the Mach number : is the velocity of the object relative to the medium used and : is the velocity of sound in the medium Mach number is the number of times the speed of sound an object or a duct, or the fluid medium itself, move relative to each other. It is named afteran Austrian physicist Ernst Mach.
The maximum speed that a vessel will achieve relative to ground is its own maximum speed through water plus the speed of the the moving water downstream.
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
The current speed is about 4 miles per hour.
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
Speed must be specified relative to something. Relative to the Sun, the speed of Earth is about 30 km/second. Relative to the Milky Way, or relative to the Local Group, you would get different numbers.
Mass IS relative to the speed you are going.
The answer depends on relative to what!
The relative refractive index tells the speed of light in a vaccum over the speed of light in medium.
the answer is relative.. if you are standing on the same train, for you the man will be running as fast as it would do on the ground. If you are standing on the ground, then his speed relative to you will be the composition of the train speed + his speed. to make it more interesting.. think now that the train it's running with a speed that approach the speed of light relative to you.
No, distance and speed are two separate measurements. Distance is how far an object moves relative to speed and time, and speed is how fast an object moves relative to time and distance.
Speed is relative to the speed of light and gravity. So gravity could effect speed.
They Both run... Get it!
An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.
Relative for starters means exact or close to. Wind Speed is how fast the air is blowing. It other words, this would mean an estimate or exact measurement to the Wind Speed.
Relative to the car you are motionless. Relative to the road you are moving at the speed of the car. Relative to the sun you are moving at the speed of Earth as it orbits the sun (30km a second).
