Question

10. What do you understand by non-uniform motion? Explain, average velocity and instantaneous
velocity of an object moving along a straight line.​

Answer 1

Answer:

Explanation:

Variable velocity: When a body covers unequal distance in equal interval of time in specified direction the body is said to be moving with a variable velocity. ... The velocity possessed by a body at some particular instant when actually the body is moving with a variable velocity is called instantaneous velocity

Answer 2

NON - UNIFORM MOTION :

Motion of an object is said to be non uniform motion when it's velocity is changing .

Change in velocity takes in 3 ways :

✳ speed changes with direction remaining constant .

✳ direction of motion changes with speed remaining constant .

✳ both direction and speed change simultaneously .

AVERAGE VELOCITY :

the distance covered by an object in unit time is called average speed .

Average velocity = total distance \ time taken

INSTANTANEOUS SPEED :

The speed of a body at any instant by looking at its speedometer . the speed at any instant is called instantaneous speed .
