Anything that comes to have "mass" - that is, a certain amount of matter contained in a body - has an attraction towards the center of the planet. is the force that pulls objects toward earth. Gravity is the force by which a planet or other body draws objects toward its center. Gravity is a force that attracts all objects towards each other every object with mass pulls on every other object with mass. Heat is anything that has mass and takes up space. For both of these interactions, we may define a force field in the following way: A force field is a region in space produced by a source such that a test object placed in its vicinity will either be attracted or repelled to the source. if an object is moved from Earth to a place with greater gravitational force. Gravity is measured as how fast objects accelerate towards each other. If it is due to mass, then it is known as We can use Newton's second law to determine the force since we know the mass and acceleration of the vehicle. Force is an important concept as it influences motion. how does the gravitational force between 2 objects that are close together compare to the gravitational force between 2 objects as they move farther apart? But the simple definition of force is that it is the push or pull experienced by any object. The motion of a falling object when the only force acting in it is gravity. and more.
