Zorluk: KolayCircular Motion and Centripetal Force

In a mechanical system where a solid weight is swung in a horizontal circle on a tether, match each observed physical action or effect with the correct physics terminology.

  • The physical string pulling the weight inward to maintain the circular curveCentripetal force
  • The direction the weight travels immediately if the tether snapsTangential path
  • The weight's physical resistance to changing its straight-line motionInertia
  • The apparent outward push experienced when observing from the rotating weight's perspectiveCentrifugal effect

Cevap

The correct pairings match the inward pull to centripetal force, the release direction to tangential path, the resistance to turning to inertia, and the outward sensation to the centrifugal effect.
In circular motion, the tether provides an inward centripetal force. Inertia is the mass's resistance to turning, causing the centrifugal effect (outward sensation). If the tether breaks, this inertia carries the mass in a straight tangential path.

Adım Adım Çözüm

1
Analyze the inward pulling force described in the first scenario.
Matches with 'Centripetal force'.
By definition, the net inward force keeping an object in circular motion is the centripetal force.
2
Determine the path of the object if the tether breaks.
Matches with 'Tangential path'.
Newton's First Law states an object will move in a straight line if no net force acts upon it, making its path tangent to the circle.
3
Identify the property causing resistance to turning.
Matches with 'Inertia'.
Inertia is the fundamental resistance of mass to any change in its state of motion.
4
Identify the term for the apparent outward push.
Matches with 'Centrifugal effect'.
The sensation of being thrown outward is a perceived effect in a rotating frame, known as the centrifugal effect.
