CHP 11 ROTATIONAL EQUILIBRIUM flashcardizz review

Front

What is stable equilibrium?

Back

Stable equilibrium is a state where an object returns to its original position after being slightly displaced.

Front

What is the center of gravity?

Back

The center of gravity is the point in an object where the weight is evenly distributed and balanced.

Front

What is neutral equilibrium?

Back

Neutral equilibrium occurs when an object remains in the same position after being displaced, with no tendency to return to its original position.

Front

What is torque?

Back

Torque is a measure of the rotational force applied to an object, calculated as the product of force and the distance from the pivot point.

Front

How does the position of the center of gravity affect stability?

Back

An object is more stable if its center of gravity is low and centered over its base of support.

Front

What is rotational equilibrium?

Back

Rotational equilibrium occurs when the sum of all torques acting on an object is zero, resulting in no angular acceleration.

Front

What is the role of the fulcrum in a seesaw?

Back

The fulcrum is the pivot point around which the seesaw rotates, and it is crucial for balancing the torques on either side.

Front

What happens when the torques on a seesaw are unbalanced?

Back

When the torques are unbalanced, the seesaw will rotate towards the side with the greater torque.

Front

Can an object in stable equilibrium be toppled easily?

Back

No, an object in stable equilibrium cannot be easily toppled; it will return to its original position after a slight disturbance.

Front

What is the significance of applying force at the center of gravity?

Back

Applying force at the center of gravity allows an object to be balanced without tipping over.
