Question

When the radius of the circular path of rotational motion increases, what happens to the arc length for a given angle of rotation?

a) Increases

b) Decreases

c) Remains the same

d) Depends on the angle of rotation

Answer 1

When the radius of the circular path of rotational motion increases, the arc length for a given angle of rotation also increases.

Step-by-step explanation:

The correct answer is a) Increases. When the radius of the circular path of rotational motion increases, the arc length for a given angle of rotation also increases. The arc length is directly proportional to the radius of the circular path, meaning that as the radius increases, the arc length increases as well.
