The _______ circular motion describes as the motion of an object in a circular path with a _______ speed. Fill in the blank.
- a)Non-uniform, constant
- b)Uniform, constant
- c)Non-uniform, varying
- d)Uniform, Varying
Correct answer is option 'B,C'. Can you explain this answer?
Verified Answer
The _______ circular motion describes as the motion of an object in a ...
Therefore, the correct multiple answers are:
2. Uniform, constant
3. Non-uniform, varying
3. Non-uniform, varying
Non-uniform, constant – This is incorrect. If the motion is non-uniform, the speed cannot be constant.
Uniform, constant – This is correct. In uniform circular motion, the speed is constant.
Non-uniform, varying – This is correct. In non-uniform circular motion, the speed varies.
Uniform, varying – This is incorrect. If the motion is uniform, the speed must remain constant, so it cannot be varying.

Understanding Circular Motion
Circular motion can be categorized into two types based on the speed of the object moving along the circular path: uniform and non-uniform circular motion.
Uniform Circular Motion
- Definition: This occurs when an object moves in a circular path at a constant speed.
- Key Characteristics:
- The magnitude of the velocity remains constant.
- The direction of the velocity changes continuously, which implies that the object is accelerating towards the center of the circle (centripetal acceleration).
- An example is a satellite orbiting Earth at a fixed speed.
Non-Uniform Circular Motion
- Definition: This involves an object moving in a circular path but with varying speed.
- Key Characteristics:
- The speed of the object changes; it can either accelerate or decelerate.
- The object experiences both centripetal acceleration (due to changing direction) and tangential acceleration (due to changing speed).
- An example includes a car taking a curve while speeding up or slowing down.
Correct Answer Explanation
The question allows for two correct options:
- Option B: Uniform, Constant
- This describes the scenario where an object maintains a constant speed in a circular path.
- Option C: Non-uniform, Varying
- This describes the scenario where the speed of the object changes while still moving in a circular path.
Both options reflect different characteristics of circular motion, making them valid answers depending on the context. Understanding these types is crucial for analyzing motion in physics.
