Question: In uniform circular motion, which of the following statements is true?

Options:

Correct Answer: Speed is constant

Solution:

In uniform circular motion, speed is constant but velocity changes due to direction change.

In uniform circular motion, which of the following statements is true?

In uniform circular motion, which of the following statements is true?

Step 1: Understand what uniform circular motion means. It is when an object moves in a circle at a constant speed.
Step 2: Recognize that speed is the distance traveled over time and remains the same in uniform circular motion.
Step 3: Learn that velocity is speed with a direction. Since the object is moving in a circle, its direction is constantly changing.
Step 4: Conclude that even though the speed is constant, the velocity changes because the direction of motion changes.

Uniform Circular Motion – In uniform circular motion, an object moves in a circular path at a constant speed, but its velocity changes due to the continuous change in direction.
Speed vs. Velocity – Speed is a scalar quantity that remains constant in uniform circular motion, while velocity is a vector quantity that changes due to direction.
