Question

1. what are uniform motion and non uniform motion ?
2. write the formula for the following
a] average speed
b]average velocity ​

Answer 1

Answer:

1. When an object covers unequal distance in equal interval of time, the motion is called non-uniform Motion .Motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
2. (a) total distance/total time taken
3. (b) total displacement/total time taken

Answer 2

Answer:

1. Uniform motion-When a body moves along a straight line with uniform speed or steady speed is called Uniform motion.

Non - uniform motion - When a body moves along a straight line but with variable or change in speed is called non-uniform motion.

2. Average speed - Distance / Time

Average velocity- u + at

(u = initial velocity ; a = acceleration ; t = time)
