When a bullet is fired from a gun, it typically moves in a straight line in the direction of the force applied by the gunpowder's explosion. This is known as rectilinear motion, which refers to motion along a straight path.
- A: Non-periodic motion refers to motion that does not repeat at regular intervals, which could describe some random or irregular movements, but the bullet's motion is more specific.
- C: Random motion refers to motion without a definite pattern or direction, which does not apply to a bullet's path.
- D: Circulatory motion is not a term used in the context of a bullet's movement, as a bullet moves in a straight line, not in a circular path.
Therefore, the bullet exhibits rectilinear motion.

Understanding Bullet Motion
When a bullet is fired from a gun, it exhibits a specific type of motion. The correct answer to the question is option B: rectilinear motion. Here’s why:
Definition of Rectilinear Motion
- Rectilinear motion refers to movement along a straight line. This type of motion is characterized by a constant direction and does not involve any curvature.
Bullet's Trajectory
- When a bullet is fired, it travels in a straight path due to the force exerted by the gunpowder explosion inside the gun's chamber.
- The bullet moves forward rapidly and maintains this direction until it encounters resistance, such as air or an object.
Factors Contributing to Rectilinear Motion
- Force Exerted by Gunpowder: The explosion pushes the bullet forward in a straight line.
- Gravity: Though gravity acts on the bullet, it does not alter its straight-line path initially; instead, it gradually affects the bullet's vertical position as it travels.
Comparison with Other Motions
- Non-periodic Motion: This refers to motion that does not repeat at regular intervals, which does not apply here.
- Random Motion: This involves unpredictable movements in various directions, unlike the straight path of a bullet.
- Circulatory Motion: This involves movement along a circular path, clearly different from the bullet's straight trajectory.
Conclusion
In summary, when a bullet is fired from a gun, it travels in a straight line, which is why it is classified as rectilinear motion. Understanding these concepts helps in grasping the basic principles of physics related to motion.
