Answer 1

Answer:

The type of motion in which the object travels with uniform speed is called Uniform motion. This means that the velocity of the body remains constant as it covers equal distances in equal intervals of time. In the case of uniform rectilinear motion, the acceleration of the body will be zero. Here, the average speed of the object will be equal to the actual speed. The examples of uniform motion are movements of hands of a clock, rotation and revolution of the earth, etc.
