Random motion

Random motion occurs for one of two reasons.

Some motion is unpredictable in theory and is truly random. For example, the motion of the electron in an atom is fundamentally unpredictable because of a weird conspiracy of nature described by quantum mechanics. The harder you try to locate the electron, the less you know about its velocity. The harder you try to measure its velocity, the less you know about its location. This is fundamental quality of small objects like electrons and there is no way around it. Although the electron is often said to "orbit" the nucleus of an atom, strictly speaking, this isn't true. The probability of finding the electron at any particular point in space is predictable, but how it got from the first place you observed it to the second is actually a meaningless question. There is no name for this kind of motion because the concept of motion doesn't even apply.

• Slow and Fast Motion: If an object covers a distance in less time and another object covers the same distance in more time, the first object  is called a faster moving object and second types of object is called a slower moving object. In other words, first object  has faster motion and second object  has slower motion
• Uniform motion: Itis motion at a constant speed in a straight line or an object that is in motion will not change its velocity unless an unbalanced force acts upon it  Example: a rolling ball.
