Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

How does gravity affect the formation of celestial bodies?

Back

Gravity pulls objects together, leading to the formation of planets and stars.

Front

What is the Law of Universal Gravitation?

Back

The Law of Universal Gravitation states that every mass attracts every other mass in the universe, and the force of attraction is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Front

How does the Law of Universal Gravitation affect planetary motion?

Back

It keeps planets in orbit around the Sun due to gravitational attraction.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.

Front

How does the electromagnetic spectrum help in studying planets?

Back

It allows us to analyze different wavelengths to gain insights into planetary surfaces and atmospheres.

Front

What is a revolution period in astronomy?

Back

The revolution period is the time it takes for a celestial body to complete one orbit around another body, such as a planet around the Sun.

Front

How does Mercury's revolution period compare to Earth's?

Back

Mercury takes less time to revolve around the Sun than Earth.

Front

What advancements in technology could improve space missions?

Back

Advancements can enhance communication, data analysis, and sample collection capabilities.

Front

What is the significance of studying the solar system?

Back

Studying the solar system helps us understand the formation, evolution, and dynamics of celestial bodies and their interactions.
