NCERT Solutions for Class 9 explains motion in terms of distance moved or displacement. Uniform and non-uniform motions of objects are explained through the graph and examples. Uniform circular motion concept is made understandable in a simple way.
1. Distance is the actual length of the path travelled by the particle in a given interval of time. Displacement is the shortest distance between the initial position and the final position of the moving particle in a particular direction. 2. Distance travelled by the particle in a given interval of time is always positive.
Distance in physics, is the length of the path (the line or curve) described by an object moving through space. Distance is independent of direction. Thus, such physical quantities that do not require direction for their complete description are called scalars.
Motion is all around us, from moving cars to flying aeroplanes. Motion can have different features like speed, direction, acceleration, etc. In this chapter, we will understand these features in detail and see how it can help us predict the future of these moving things.

30 cze 2021 · Path length (or distance) : The actual path or length travelled by a object during its journey from its initial position to its final position is called the distance. Note: (i) Distance is a scalar quantity which requires only magnitude but no direction. Example, Manju travelled 65 km. (ii) Distance is measured by odometer in vehicles.
