Understanding Gravitational Force

What is gravitational force?

• Gravitational force only acts on objects in motion.

• Gravitational force is the force that keeps objects in a straight line.

• Gravitational force is a repulsive force between two masses.

• Gravitational force is the attraction between two masses.

Who formulated the law of universal gravitation?

• Sir Isaac Newton

• Albert Einstein

• Galileo Galilei

• Niels Bohr

What is the formula for gravitational force?

• F = G * (m1 + m2) / r

• F = m1 * m2 / G * r

• F = G * (m1 * m2) / r^2

• F = G * m1 * m2 * r^2

Which of the following has the strongest gravitational pull?

• Red giant

• Black hole

• White dwarf

• Neutron star

How does distance affect gravitational force?

• Gravitational force is independent of distance.

• Distance increases gravitational force.

• Distance has no effect on gravitational force.

• Distance decreases gravitational force.

What is the gravitational force on Earth?

• 9.81 kg

• 9.81 m/s

• 9.81 N

• 9.81 m/s²

Which planet has the strongest gravitational force?

• Earth

• Jupiter

• Venus

• Mars

What happens to gravitational force if mass increases?

• Gravitational force remains the same regardless of mass.

• Gravitational force decreases if mass increases.

• Gravitational force increases if mass increases.

• Gravitational force is unaffected by changes in mass.

Is gravitational force a contact force?

• Yes, gravitational force is a contact force.

• Gravitational force requires physical touch to exert influence.

• Gravitational force only acts at a distance.

• No, gravitational force is not a contact force.

Does gravitational force act on all objects?

• Yes, gravitational force acts on all objects.

• Gravitational force is negligible for all objects.

• Only celestial bodies experience gravitational force.

• Gravitational force only acts on large objects.
