Strategies for … WebSep 10, 2024 · Solutions. We know that slope of distance-time graph represent the speed. In distance-time graph C, the speed of the object is constant for some time as the slope of distance-time curve is constant for some time. After some point of time, its slope increases. This means that the speed of object changes and object accelerates.

T ( f) is the final time and t ( i) is the initial time. Some other things to keep in mind when using the acceleration equation: You need to subtract the initial velocity from the final velocity.
WebThe speed of an object can be positive or zero but not negative. Speed formula. Speed(v) = Distance travelled (s) / Time taken (t) Types of speed. 1. Uniform speed or Constant speed If an object covers equal distances in equal intervals of time, then its speed is called uniform speed or constant speed. 2. Non-uniform speed or Variable speed. WebAug 28, 2024 · The time rate of change of position of the object in any direction is called speed of the object. Speed Formula in Physics Its SI unit is m/s. It is a scalar quantity.

WebWave speed is the distance the wave travels in a given amount of time, such as the number of meters it travels per second. The equation that represents the wave speed is given as follows: S p e e d = D i s t a n c e T i m e.
