Question

For each of the following rotating objects,describe the direction of angular momentum vector. A)the minute hand of a clock -towards the mechanism of the clock -towards the glass of the clock B)the right front tire of a car moving backwards -to the right, away from the car -to the left, towards the center of the car C)an ice skater spinning clockwise -downward -upward D)the earth, rotating on its axis -out of the earth's south pole -out of the earth's north pole

Answer 1

The direction of the angular momentum vector for each object can be determined using the right-hand rule.

Step-by-step explanation:

The direction of the angular momentum vector can be determined using the right-hand rule. When the minute hand of a clock is rotating, the direction of its angular momentum is towards the mechanism of the clock or inward. For the right front tire of a car moving backwards, the direction of its angular momentum is to the right, away from the car. When an ice skater is spinning clockwise, their angular momentum vector is upward or against gravity. Lastly, when the Earth is rotating on its axis, the direction of its angular momentum is out of the Earth's north pole.

Answer 2

The direction of the angular momentum vector can be determined using the right-hand rule. The direction depends on the direction of rotation of the object.

Step-by-step explanation:

For each of the following rotating objects, the direction of the angular momentum vector can be determined using the right-hand rule. The right-hand rule states that if you curl your fingers in the direction of the rotation, your thumb points in the direction of the angular momentum vector.

A) The minute hand of a clock rotates counterclockwise, so the angular momentum vector points towards the mechanism of the clock.

B) The right front tire of a car moving backwards rotates counterclockwise, so the angular momentum vector points to the right, away from the car.

C) An ice skater spinning clockwise has a counterclockwise rotation, so the angular momentum vector points downward.

D) The Earth rotating on its axis has a counterclockwise rotation when viewed from the north pole, so the angular momentum vector points out of the Earth's north pole.
