Question

24. Give one example of each of the following:
(a) uniform velocity (b) variable velocity
(c) variable acceleration (d) uniform retardation.​

Answer 1

Answer:

a) A car moving on a straight road with constant speed has uniform velocity

b) A rotating fan at a constant speed has variable velocity, because of continuous change in direction

c) a car is moving in a crowded street, when car find space it will move with greater speed and if it stuck in crowd then it will move with less speed.

d) a car moving with velocity 'v' is brought to rest by applying brakes, then such a motion is an example of uniform retardation

Answer 2

Answer:

a) an example of uniform velocity is (motion of a car with constant speed)

b) an example of variable velocity is (motion of a car with different velocities)

c) a example of variable acceleration is ( motion of a car with different acceleration)

d) an example of uniform retardation is ( stopping of a car with the same(constant) acceleration)
