• D. 1 and 2

Answer 1

The correct option is C 1 and 3

The movement of an object is called motion and an object is said to be in motion when its position changes with time.
If an object moves very fast then its movement can be observed easily but if an object moves very slowly, then it becomes difficult to observe its movement immediately.
Motion in a straight line is called rectilinear motion. Example: the movement of a bullet fired from a gun is an example of rectilinear motion.
Rectilinear motion takes place in a fixed direction.
The motion which repeats itself after regular intervals of time is called periodic motion.
