Force
Force, in physics, any action or influence that accelerates an object. Force is a vector , which means that it has both direction and magnitude. When several forces act on an object, the forces can be combined to give a net force. The net force acting on an object, the object's mass , and the acceleration of the object are all related to each other by Newton's second law of motion, named after English physicist and mathematician Isaac Newton . The second law of motion states that the acceleration an object experiences multiplied by the mass of the object is equal to the net force acting on an object. Thus, if a given force acts on two objects of different mass, the object with a larger mass will have a lower acceleration. See Mechanics . An object experiences a force when it is pushed or pulled by another object. For example, shoving a stationary shopping cart applies a force that causes the shopping cart to accelerate. An object can also experience a force because of the infl
