Understanding Gravity and Relativity

According to Newton, what happens to the gravitational force as the distance between two masses increases?

• It increases.

• It decreases.

• It doubles.

• It remains constant.

What was the main confusion about Newton's theory of gravity?

• How the moon orbits the Earth.

• Why the Earth orbits the Sun.

• How gravity works over large distances.

• Why objects fall to the ground.

What does Einstein propose about the nature of gravity?

• Gravity is a force.

• Gravity is a magnetic field.

• Gravity is an illusion.

• Gravity is a curvature of space-time.

In Einstein's analogy, what happens to a skinny man on a fabric mat when a fat man sits in the middle?

• The skinny man is pushed upwards.

• The skinny man is pulled towards the fat man.

• The skinny man moves away.

• The skinny man remains stationary.

What is the equivalence principle demonstrated by Einstein's thought experiments?

• Light and sound are equivalent.

• Acceleration and gravity are equivalent.

• Time and space are equivalent.

• Mass and energy are equivalent.

What happens to a ball in an accelerating lift according to Einstein's thought experiment?

• It floats in the air.

• It moves in a straight line.

• It falls to the floor.

• It moves upwards.

How does light behave in a strong gravitational field according to Einstein?

• It travels faster.

• It splits into colors.

• It bends.

• It stops.

What was the significance of Arthur Eddington's experiment during the solar eclipse?

• It confirmed the bending of light by gravity.

• It demonstrated the speed of light.

• It showed that stars are closer than they appear.

• It disproved Einstein's theory.

What did Eddington's team observe during the solar eclipse that supported Einstein's theory?

• The moon's orbit changed.

• The sun's brightness decreased.

• Stars appeared in unexpected positions.

• The sun's gravity increased.

What is the general theory of relativity primarily about?

• The curvature of space-time.

• The expansion of the universe.

• The speed of light.

• The nature of black holes.
