What is uniform circular motion?
What is uniform circular motion?
- When an object moves in a circular path with a constant speed (correct)
- When an object moves in a straight path at varying speeds
- When an object moves in a straight path with a constant speed
- When an object moves in a circular path with a varying speed
In uniform circular motion, what is the difference between a scalar and vector quantity?
In uniform circular motion, what is the difference between a scalar and vector quantity?
- Scalar quantities and vector quantities are the same in uniform circular motion
- Scalar quantities require only direction, while vector quantities require magnitude and direction
- Scalar quantities require both magnitude and direction, while vector quantities require only magnitude
- Scalar quantities are described with only magnitude, while vector quantities need both magnitude and direction (correct)
Why does velocity change in uniform circular motion even if the speed is constant?
Why does velocity change in uniform circular motion even if the speed is constant?
- Due to changes in the object's speed
- Due to changes in the object's mass
- Due to changes in the object's direction (correct)
- Due to changes in the object's volume
