Gravedad: la fuerza de atracción universal

The transcript explains gravitational force, highlighting its weak nature and significant impact only on objects with considerable mass. It describes how gravity is responsible for the orbits of planets around the Sun and the Moon around the Earth, as well as preventing us from floating into space.

What is the relationship between gravitational force and the masses involved?

• It is proportional to the square of the masses.

• It is unrelated to the masses.

• It is directly proportional to the masses.

• It is inversely proportional to the masses.

Why is gravitational force considered relatively weak?

• Because it only affects small objects.

• Because it is stronger than electromagnetic force.

• Because it is only significant for objects with large mass.

• Because it does not affect celestial bodies.

Which of the following is NOT a result of gravitational force?

• Planets orbiting the Sun.

• People staying grounded on Earth.

• Objects floating in space.

• The Moon orbiting the Earth.

What role does gravity play in the movement of celestial bodies?

• It repels them from each other.

• It causes them to move in straight lines.

• It keeps them stationary.

• It causes them to revolve around larger bodies.

How does gravity prevent us from floating into space?

• By exerting a downward force.

• By creating a magnetic field.

• By increasing our mass.

• By pushing us downwards.
