1.	Explain and giving one example of each.(1) Uniform linear motion(2) Non-uniform linear motion(3) Non-linear motion(4) Speed
Answer» (1) Uniform linear motion : When the distance traversed by an object along a straight line in unit time is the same, the motion is called as uniform linear motion, e.g. Motion of soldiers on parade. (2) Non-uniform linear motion : When the distance traversed by an object along a straight line in unit time keeps on changing, the motion is called non-uniform linear motion. e.g. A girl coming down a slide. (3) Non-linear motion : The motion of an object that does not move in a straight line is called non-linear motion. e.g. Motion of a swing, (4) Speed : The distance traversed by an object in unit time is called the speed of that object. e.g. A boy riding on a bicycle covers a distance of 15 kilometres in 3 hours. Hence, Speed = \(\frac{15}{3}\) = 5 kilometres/hour

Answer»

(1) Uniform linear motion :

When the distance traversed by an object along a straight line in unit time is the same, the motion is called as uniform linear motion,

e.g. Motion of soldiers on parade.

(2) Non-uniform linear motion :

When the distance traversed by an object along a straight line in unit time keeps on changing, the motion is called non-uniform linear motion.

e.g. A girl coming down a slide.

(3) Non-linear motion :

The motion of an object that does not move in a straight line is called non-linear motion.

e.g. Motion of a swing,

(4) Speed :

The distance traversed by an object in unit time is called the speed of that object.

e.g. A boy riding on a bicycle covers a distance of 15 kilometres in 3 hours.

Hence,

Speed = \(\frac{15}{3}\)

= 5 kilometres/hour
