what is the formula for finding an objects speed. In this article we will discuss the concept and relationship of speed time and distance. C the speed of light 300000 kms or 30 x 10 8 ms the wavelength of light usually measured in meters or Angstroems 1 A 10-10 m.

S speed meterssecond. At a distance r from the center of the rotation a point on the object has a linear speed equal to the angular speed multiplied by the distance r. Uniform speed variable speed average speed and instantaneous speed.
The other formula if you have the initial and final speed add the two together and divide by 2.
In our example 100 miles2 hours 50 mileshour about 80 kilometershour. X Research source In these types of problems It doesnt matter for how long each speed is driven as long as each speed is used for half the total duration of time. The free fall speed formula is the product of gravitational constant which is 98 ms 2 and the time taken for the object to reach earths surface. It is the change in the position of an object with respect to time.
