Gravitational force is a non-contact force. It depends. It aids with the visualisation of abstract physical concepts. Even if an object is initially at rest, we regard the force applied to an object to get it to move as a pushing force because the direction of the force vector aligns with the vector of the object's resulting velocity. Let's finish this explanation by considering some examples involving pulling forces. If a net force is exerted on an object the velocity of the object will change because a net force exerted on an object may make its velocity increase. The more heat is transferred to an object, Sometimes, force is simply defined as a push or pull upon an object resulting from the objects interaction with another object.
