The force of gravity also gets weaker with distance. And if you were on a planet with less mass than Earth, you would weigh less than you do here. All its mass makes a combined gravitational pull on all the mass in your body. The closer you are to an object, the stronger its gravity is.Įarth’s gravity comes from all its mass. The more mass an object has, the more gravity it has. The strength of gravity depends on two things: the mass of the object and the distance between the objects.
Earth’s gravity keeps you on the ground and makes things fall. The strength of gravity keeps all of the planets in orbit around the sun. Gravity is the force by which a planet or other body draws objects toward its center. Now that we have a brief understanding of the three laws of motion, we can better understand the definition of gravity. The third law, known as the law of action and reaction, says that for every action, there is an equal and opposite reaction. The second law, known as the law of acceleration, states that the acceleration of an object is proportional to the force acting on it. The first law, the law of inertia, states that an object will remain at rest or in motion unless acted on by an outside force. These laws, put, describe how objects move. To understand the definition of gravity, one must first understand the three laws of motion. But that’s what I’m going to talk about today is the most popular force, “Gravity.” Definition of gravity: And the rest of them are different types of troops. Many are attraction forces by which two or more bodies come closer. As we all studied in our school life, many types of powerful forces exist in this universe, like electric force, magnetic force, friction force, viscous force, etc.
