What is the main difference between vibration and oscillation?

Oscillations and vibrations both are the examples of to and fro motion. The vibrations are very small in amplitude compare to oscillations. Amplitude is the distance travelled by the vibrating object either side from its mean position. The vibrations called as oscillations once the amplitude becomes large.

Give one example for each of the following. Rotational motion Circular motion Compound motion.

Motion is the rate of change of position of an object with respect to the time and surroundings. The motion of an object along a circular path in a fixed orbit is known as rotational motion. It's also known as a body's motion in which all the particles travel in a circular motion. Eg: Rotation of the earth on its own axis. A circular motion is defined as a body movement that follows a circular path. Uniform circular motion is the motion of a body travelling at a constant speed along a circular path. Eg: The motion of a car on a curved road. A motion that is a combination of rotational and translational motion is a compound or combined motion. Eg : A wheel rolling down the road.
