Question

multiple - choice question
\if the speed of the steam engine increases,__________force causes two rotating masses to move outwards.\
centrifugal
circular
centripetal
rewatch

Explanation:

To solve this, we analyze the forces:

• Centrifugal force is an apparent force in a rotating frame, acting outward from the center of rotation. As the speed of rotation (of the steam engine's rotating masses) increases, centrifugal force makes them move outwards.
• "Circular" is not a specific force type here.
• Centripetal force acts towards the center of rotation, so it would pull masses inward, not outward.

So the correct term is "centrifugal".

Answer:

A. centrifugal
