Document Summary
When an object rests or pushes on a surface, the surface exerts a push on it that is perpendicular to the surface. Force exerted on an object on a surface that runs parallel to the surface. A pulling force exerted on an object by a rope, cord, string, etc. The pull of gravity on an object. Long range force (can act over a distance) Note: several forces acting at a point on an object have the same as the vector sum at the same point. An object will remain in its current state of motion unless another force acts on it. Only valid from an inertial frame of reference (non-accelerating viewpoint) The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to the mass of the object. A constant net force causes a constant acceleration. Doubling the net force doubles the acceleration.
