When an object travels in a straight line in uniform motion, the distance it has traveled can be calculated by multiplying the velocity by the time it took to travel the distance. An example of non-uniform motion is a body rotating at a constant speed. Note: If rate of change of any quantity with time is constant, it is said to be Uniform. Rotational. Here in class 9 physics chapter 8 of NCERT book we will study this topic in some more detail. Since mass is a measure of inertia of a body and object B has greater mass, so it will have greater inertia. Since, the speed i.e., the distance covered per unit time for the entire distance covered is not the same, therefore, the motion is a non-uniform motion. Solution 6 (Num) The basic difference between uniform and non uniform motion is that: In uniform motion, a body moves with a constant speed such as the Motion of earth around the sun. Uniform speed is a scalar quantity,only magnitude is present and no directions. While in non-uniform motion a body moves with a variable speed such as a Horse running in the race.

Question 16: State whether force is a scalar or a vector quantity. The average velocity formula describes the relationship between the length of your route and the time it takes to travel. We have 950 N - 730 N = 220 N to the right as the resultant force. Uniform Circular Motion. Uniform motion describes a small set of circumstances because, in real life, most movement is not observed at a constant speed or direction. An object having uniform motion travels equal distances in equal intervals of time. 2009 Edition Chapter 9C. Another player kicks the ball towards the goal post. It is a scalar quantity.
