Answer:
1.a linear motion in which the direction of the velocity remains constant and the path is a straight line.
2.Rotational motion can be defined as a motion of an object around a circular path, in a fixed orbit. It can also be defined as the motion of a body, in which all of its particles move in a circular motion with a common angular velocity, about a fixed point—for example, the rotation of Earth about its axis.
3.circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
4.Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.
5.The motion in which certain part or parts of a body always remain fixed and do not move while the rest of the body moves to and fro in a definite style is called vibratory motion
