Rotational Motion

What is rotational motion?

• The motion of an object moving in a straight line.

• The motion of an object around a fixed point.

• The motion of an object spinning around an axis.

• The motion of an object under the influence of gravity.

Which of the following can be considered as an example of rotational motion?

• A car moving down the street.

• A Ferris wheel turning.

• A leaf falling from a tree.

• A person walking in a straight line.

What is the axis of rotation in rotational motion?

• The point at which the object is heaviest.

• The line about which the rotation occurs.

• The outer edge of the rotating object.

• The geometric center of the space occupied by the object.

What is the line called that is perpendicular to the side of the Ferris wheel and passes through the wheel's center?

• Diameter

• Radius

• Chord

• Tangent

How can the distance traveled by an object on the edge of the Ferris wheel be measured?

• Calculating the circumference of the wheel

• Measuring the diameter of the wheel

• Estimating the height of the wheel

• Counting the number of rotations

What type of motion does a point on an object undergo when it rotates about a single axis?

• Linear motion

• Circular motion

• Random motion

• Oscillatory motion

What describes the motion of a light bulb on a Ferris wheel according to the image provided?

• The light bulb moves in a straight line from the center.

• The light bulb remains stationary at one point on the Ferris wheel.

• The light bulb moves about the axis in a circle of radius r.

• The light bulb oscillates back and forth along the radius.

What is essential to set up when analyzing rotational motion according to the text?

• A) A variable reference point

• B) A fixed reference line

• C) A moving axis

• D) A dynamic timeline

What happens to the bulb after a time interval Δt in rotational motion?

• It returns to its original position

• It moves to a new position

• It stops moving

• It moves in a straight line

In the context of rotational motion, what does the variable 's' represent in the diagram provided?

• The radius of the circle

• The angle in radians

• The arc length

• The diameter of the circle
