A contact pulling force, as the name implies, is one in which the agent responsible for exerting the force on the object is in direct contact with it. generally the above force is known as attractive force. 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. See answer. how does the law of universal gravitation explain why gravity between an elephant and Earth is greater than gravity between a cat and Earth? The reason for this is that we may distinguish between two types of pulling forces: contact pulling forces or long-range pulling forces. the closer the stronger the gravitational force. The moment you push against it, it tends to resist and react or spring back with the same magnitude. At some angle, the torque equals the gravitational force.

Test your knowledge with gamified quizzes. The force that pulls objects towards each other. Its 100% free. The gravity well is a physics analogy. the mass of most objects is too small to cause a force large enough to move objects toward each other. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Remember that Newton's first law of motion or law of inertia says an object in a state of rest continues to be in a state of rest or moves with uniform velocity until an external unbalanced force acts on it.
