Earth's Rotation and Gravity Concepts

The video tutorial by Che Gudila covers the topic of Earth and its gravitational pull, explaining how gravity affects objects on Earth. It discusses the importance of gravity in keeping objects grounded and preventing them from floating. The tutorial also covers Earth's rotation and revolution, explaining how these movements result in the day and night cycle. The effects of Earth's rotation on the position of the sun and shadows are also explored, providing a comprehensive understanding of these fundamental concepts.

What causes objects to fall towards the ground on Earth?

• Friction

• Gravity

• Wind resistance

• Magnetic force

What would happen to objects on Earth without gravitational pull?

• They would move sideways

• They would sink into the ground

• They would float in the air

• They would remain in place

How does Earth move around the Sun?

• In a circular orbit

• In a square orbit

• In an elliptical orbit

• In a triangular orbit

How long does it take for Earth to complete one rotation on its axis?

• 365 days

Why is it daytime in Malaysia but nighttime in San Francisco at the same time?

• Because of Earth's rotation on its axis

• Because of the Sun's movement
