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 due to gravity on an object.
The fundamental SI unit of mass. One kilogram (symbol kg) is the mass of 1 liter (1 L) of water at 4° C.
The SI unit of force. One newton (symbol N) is the force that will give an object of mass 1 kg an acceleration of 1m/s².
The quantity of space an object occupies.
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.
Any influence that can cause an object to be accelerated, measured in newtons (or in pounds, in the British system).
Motion under the influence of gravitational pull only.
The speed at which the acceleration of a falling object terminates because air resistance balances its weight. When direction is specified, then we speak of terminal velocity.
Terminal speed together with the direction of motion (down falling objects).
acceleration ~ net force
An object's acceleration is directly proportional to the net force acting on it.
Force between two objects at relative rest by virtue of contact that tends to oppose sliding.
Contact force produced by the rubbing together of the surface of a moving object with the material over which it slides.
air resistance (a.k.a. air drag)
Friction, or drag, that acts on something moving through air.
Anything that flows; in particular, any liquid or gas.
Acceleration ~ 1/ mass
For a given force, the acceleration produced is inversely proportional to the mass.
The two values change in opposite directions. (As the denominator increases, the whole quantity decreases. For example, the quantity 1/100 is less than 1/10.
