CHP 11 ROTATIONAL EQUILIBRIUM flashcardizz review

Front

What is neutral equilibrium?

Back

A state where an object remains in equilibrium regardless of its displacement; any movement does not raise or lower its center of gravity.

Front

How does the height of an object's center of gravity affect its stability?

Back

The height of an object's center of gravity does affect its stability; a lower center of gravity generally increases stability.

Front

In which food item is the center of gravity located at a point where there is no mass?

Back

Donut.

Front

What happens to an object's center of gravity when it is in stable equilibrium and displaced?

Back

The center of gravity will rise.

Front

What causes toppling in an object?

Back

Toppling occurs when there is an unbalanced torque acting on the object.

Front

Define 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

What is the difference between stable and unstable equilibrium?

Back

In stable equilibrium, an object returns to its original position after displacement; in unstable equilibrium, it moves away from its original position.

Front

What is the center of gravity?

Back

The center of gravity is the point where the weight of an object is evenly distributed in all directions.

Front

How does mass distribution affect stability?

Back

Objects with mass distributed lower to the ground tend to be more stable than those with mass higher up.

Front

What is an example of an object in unstable equilibrium?

Back

A pencil balanced on its tip.
