What is the definition of inertia?

• The force that keeps the Earth in its orbit around the Sun.
• The scientific law that states that every object in the universe attracts every other object.
• The tendency of an object to resist a change in motion.
• The attractive force between objects; the force that moves objects downhill.

What is the difference between rotation and revolution?

• Rotation is the movement of an object around another object, while revolution is the spinning motion of a planet on its axis.
• Rotation is the path of an object as it revolves around another object in space, while revolution is the spinning motion of a planet on its axis.
• Rotation is the spinning motion of a planet on its axis, while revolution is the movement of an object around another object.
• Rotation is the movement of an object around another object, while revolution is the path of an object as it revolves around another object in space.

What did Galileo Galilei contribute to the heliocentric model?

What is the definition of the term 'axis'?

• The movement of an object around another object.
• The spinning motion of a planet on its axis.
• The path of an object as it revolves around another object in space.
• An imaginary line that passes through a planet's center and its north and south poles, about which the planet rotates.

What is the cause of the seasons on Earth?
