Cards Term force Definition push or pull on an object Term contact force Definition force that arises from touching b/t two objects Term non contact force Definition force originating without the touching b/t two objects, such as gravitational force Term mass Definition an amount of matter Term Newton's first law Definition an object will maintain its inertia unless acted upon by an outside force Term inertia Definition object's tendency to remain continuously at rest or continuously in motion Term inertial reference frame Definition area surrounding an object which allows Newton's first law to be valid Term Newton's second law Definition a net force acted upon an object will cause that object to accelerate Term free body diagram Definition a vector diagram that shows forces acting on an object Term Newton's third law Definition when an object exerts force onto another object, the 2nd object exerts a force of equal magnitude but in the opposite direction Term fundamental forces Definition gravitational force strong nuclear force electroweak force Term gravitational force Definition force acting on an object due to the gravitational attraction b/t the object and the planet Term Newton's law of universal gravitaiton Definition attractive force b/t any two bodies tahat is directly proportional to mass and inversely proportional to the distance b/t the two bodies Term normal force Definition perpendicular force exerted by any surave in contact with an object Term apparent force Definition the force exerted by an object in an accelerated frame of reference Term friction Definition force that opposes motion due to imperfections b/t any surface and any object Term maximum static frictional force Definition the greatest friction a surface can present, just at the point of constant motion Term kinetic friction force Definition the amount of friction which must be overcome in order to maintain motion Term tension Definition name for a force usually associated w/ ropes or cables acting on an object Term weight Definition gravitational force due to earth Term lift Definition support force acting on an air born object Term thrust Definition force created by an engine in an airborn object
