Motion of a Stone Tied to the End of a String
When a stone is tied to the end of a string and moved with a constant angular speed in a horizontal plane about a fixed point, the type of motion observed is Uniform Circular Motion.
Explanation:
Uniform Circular Motion:
Uniform Circular Motion is a type of motion where an object moves in a circular path with a constant speed. In this type of motion, the object moves in a circular path with a fixed radius, and the speed of the object remains constant throughout the motion.
Stone Tied to the End of a String:
When a stone is tied to the end of a string and moved in a horizontal plane about a fixed point, the stone experiences a centripetal force directed towards the center of the circular path. This force is provided by the tension in the string.
Key Points:
- The stone is moving in a circular path.
- The stone is tied to the end of a string.
- The stone is moving with a constant angular speed.
- The motion is happening in a horizontal plane.
- The stone experiences a centripetal force towards the center of the circular path.
Analysis:
- The stone is constrained to move in a circular path due to the string.
- The constant angular speed indicates that the stone is moving at a constant rate along the circular path.
- The horizontal plane suggests that the motion is happening on a flat surface, parallel to the ground.
Conclusion:
Based on the given information, the type of motion observed when a stone is tied to the end of a string and moved with a constant angular speed in a horizontal plane about a fixed point is Uniform Circular Motion. In this motion, the stone moves in a circular path with a fixed radius and constant speed, experiencing a centripetal force directed towards the center of the circular path.
