Exploring Earth's Rotation and Centrifugal Force

What would happen if Superman reversed the rotation of the Earth?

• The Earth would stop rotating permanently.

• All people on Earth would die.

• Nothing significant would happen.

• Time would reverse.

What is centrifugal force?

• A fictitious force that feels like a force due to rotation.

• A force that only exists in space.

• A real force that pushes objects outward.

• A force that pulls objects inward.

Why does water stay in a bucket when spun fast enough?

• Because of gravity.

• Because of centrifugal force.

• Because of air resistance.

• Because of the bucket's shape.

Where on Earth would you feel the most centrifugal force?

• At the North Pole.

• At the South Pole.

• At the Tropic of Cancer.

• At the equator.

How does Earth's rotation affect your weight at the equator?

• You become weightless.

• Your weight remains the same.

• You weigh less at the equator.

• You weigh more at the equator.

What would happen if Earth rotated once every hour and a half?

• People would be flung into space.

• People would hover at the equator.

• People would weigh less.

• People would weigh more.

What is the shape of the Earth due to its rotation?

• Perfectly spherical.

• Prolate (stretched pole to pole).

• Oblate (flattened at the poles).

• Irregular.

What is the Coriolis force?

• A force that causes objects to move in a straight line.

• A real force that affects weather patterns.

• A fictitious force due to Earth's rotation.

• A force that only affects objects in space.
