Conceptual Physics Chapter 4: Newton's Second Law of Motion


Terms in this set (...)

A push or a pull exerted on an object, measured in newtons.
The resistive force that opposes the motion or attempted motion of an object either past another object with which it is in contact or through a fluid.
The quantity of matter in an object. More specifically, it is the measure of the inertia or sluggishness that an object exhibits in response to any effort made to start it, stop it, deflect it, or change in any way its state of motion.
The force upon an object due to gravity.
The fundamental SI unit of mass.
The SI unit of force. One newton (symbol N) is the force that will give an object of mass 1 kg an acceleration of 1 m/s^2.
Newton's second law
The acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.
Free fall
Motion under the influence of gravitational pull only.
Terminal velocity
Terminal speed with direction specified.
Net force
The combination of forces acting on an object.
The rate at which velocity changes with time.
Static Friction
Force between two objects at relevant rest by virtue of contract that tends to oppose sliding
Formula for friction force when the coefficient of friction and normal contact are given.
Air Drag
Air on something
