Speed=DistanceTime To find the speed, divide the distance by the amount of time taken. Step 4: Write the answer using the correct unit of measurement. The speed will be given in meters per second (m/s), for instance, if the distance is in meters and the time is in seconds. The spe...
The nice thing about this latter equation is that the first equation is basically just a formula for and so can be dropped, leaving us with This equation now admits a two-parameter family of scale invariances for , where we use to ednote the coordinate. It also inherits an energy conse...
Speed is measured as the ratio between the distance and time and the SI unit of speed is m/s. It is the change in the position of an object with respect to time. There are four types of speed: uniform speed, variable speed, average speed, and instantaneo
For the object to follow a circular path without changing speed, a continuous centripetal force must be applied at a right angle to its path. The radius (r) of this circle is equal to the mass (m) times the square of the velocity (v) divided by the centripetal force (F), or r = ...

With rapid economic development, the protection of the ecological environment has become very important. The modernization of rural ecological governance is the basis and prerequisite for the sustainable economic and social development of vast rural areas of China in the current era. It is urgent to...
Thus one can view (4) as a “master equation” for spherical trigonometry: in principle, it can be used to derive all the other laws of this subject. Remark 1 The law (4) has an evident symmetry , which corresponds to the operation of replacing a spherical triangle with its dual ...
General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. ...
