Gravitational Pull
The gravitational pull is the force of attraction that exists between any two objects with mass. This force is responsible for keeping the planets in orbit around the sun, pulling objects towards the Earth, and even holding our own bodies on the ground.
Key Concepts to Understand:
- Gravity: Gravity is the force that pulls objects towards each other. The larger an object's mass, the greater its gravitational pull.
- Mass: Mass is the amount of matter in an object. The greater the mass, the greater the gravitational pull.
- Distance: The gravitational pull between two objects decreases as the distance between them increases.
- Weight: Weight is the measure of the force of gravity on an object's mass. An object's weight can vary depending on the gravitational pull of the celestial body it is on.
Study Guide Questions:
- What is gravitational pull and what causes it?
- How does the mass of an object affect its gravitational pull?
- Explain how the distance between two objects affects their gravitational pull on each other.
- What is the difference between weight and mass?
- Give examples of how gravitational pull affects objects in our everyday lives.
Understanding the concept of gravitational pull is essential in comprehending many aspects of physics and astronomy. By grasping the fundamentals of this force, one can gain a deeper understanding of the universe and the forces that govern its behavior.

Second Grade: Focus on Systems and System Models; Energy and Matter
Earth and Space Sciences: Students develop an understanding of the distribution and role of water and wind in weather, shaping the land, and where organisms live. Wind and water can also change environments, and students learn humans and other organisms can change environments too. Students develop an understanding of changing patterns in the sky including the position of Sun, Moon, and stars, and the apparent shape of the Moon.
Earth and Space Standards
Develop and use models to represent that water can exist in different states and is found in oceans, glaciers, lakes, rivers, ponds, and the atmosphere.
