Speed
The velocity indicates how fast or how slow a body is moving - do my engineering assignment for me . It is a directional (vectorial) physical quantity and thus has a certain magnitude and direction at every point of the movement of a body.
Formula symbol: v
Units: one meter per second (1 m / s) one kilometer per hour (1 km / h)
When determining and specifying values for velocity, a distinction must be made between average velocity and instantaneous velocity. The velocity indicates how fast or how slow a body is moving. It is a directional (vectorial) physical quantity and thus has a certain magnitude and direction at every point of the movement of a body.
Formula symbol: v
Units: one meter per second (1 m / s) one kilometer per hour (1 km / h) The following applies to the units: 1 ms = 3.6 kmh1 kmh = 13.6ms≈0.28 ms
In shipping, the unit used is a knot (1 kn):
1 kn = 1 nautical mile1 hour = 1,852 m1 h≈ 1.85 kmh
The speed of aircraft is sometimes expressed in Mach. A Mach means that the aircraft is flying at the speed of sound:
1 Mach = 333 ms≈ 1,200 km / h
Speeds in nature and technology
In the following overview, speeds in nature and technology are given.
Average speed and instantaneous speed
In the case of velocity, a distinction must be made between average velocity and instantaneous velocity (momentary velocity). The average velocity indicates the average velocity along a distance that a body travels in a certain time - here . The instantaneous velocity indicates the velocity at a certain point in time.
Measuring velocity
The speed of a body can be measured with a speedometer or tachometer - buy assignment . A tachometer is used to measure the respective instantaneous speed.
Speed can also be measured with laser measuring devices (laser guns), with radar devices or with the help of induction loops. Detailed information can be found under the heading "Speed measurement".
