A body can undergo the following types of motion except

Analyze the question: We're asked which one is NOT a type of motion a body can undergo. So we look for the odd one out.

Concept: In Physics (WASSCE syllabus), the common types of motion of a body are:

• Translational motion: the whole body moves from one point to another (e.g., a car moving along a road).
• Rotational motion: the body spins about an axis (e.g., a spinning wheel or fan).
• Random motion: irregular, unpredictable movement (e.g., Brownian motion of smoke particles, gas molecules).
• Vibrational/oscillatory motion: to-and-fro movement about a fixed point (e.g., a pendulum).
• Circular motion and linear motion are also common.

Relative motion is different. It is not a kind of motion the body itself performs. It describes how we measure or describe motion with respect to a chosen reference point or observer. For example, a passenger in a moving bus is at rest relative to the bus but moving relative to someone on the roadside. Any type of motion (translational, rotational, random) can be described in a relative way, so it is a viewpoint, not a type of motion.

Step by step:

1. Random: a real type of motion. ✔
2. Rotational: a real type of motion. ✔
3. Translational: a real type of motion. ✔
4. Relative: a way of describing motion, not a distinct type a body undergoes. ✘

Tip: Remember the main types as T-R-V-R: Translational, Rotational, Vibrational, Random. When a question says "except," pick the term that describes a frame of reference or description (like "relative") rather than an actual movement pattern.
