The correct Answer is:
To solve the question regarding uniform circular motion, we need to analyze the concepts of speed and velocity in the context of circular motion. ### Step-by-Step Solution: 1. **Understanding Speed and Velocity**: - Speed is a scalar quantity, meaning it has magnitude but no direction. - Velocity is a vector quantity, meaning it has both magnitude and direction. 2. **Defining Uniform Circular Motion**: - In uniform circular motion, an object moves in a circular path with a constant speed. This means that the distance traveled per unit time remains the same. 3. **Analyzing Velocity in Circular Motion**: - Although the speed is constant in uniform circular motion, the direction of the object’s motion is continuously changing as it moves along the circular path. - Since velocity depends on both speed and direction, the changing direction means that the velocity is not constant. 4. **Conclusion**: - Therefore, in uniform circular motion, we have: - Constant speed (the magnitude of speed does not change). - Variable velocity (the direction of motion changes continuously). - The correct answer to the question is: **Option 1: constant speed, variable velocity**. ### Final Answer: Uniform circular motion has **constant speed and variable velocity**. ---
