FORCE (F): A force is a push or a pull on any object. All types of forces can be categorized as contact forces or as action-at-a-distance forces. The force of gravity, electrical forces, and magnetic forces are classic examples of forces which exist between two objects even when they are not physically touching.
MASS (M): The mass of an object is a measurement of the amount of material in a substance. Mass refers to how much "stuff" is there. Elephants are very massive, since they contain a lot of "stuff."
MOMENTUM: Momentum pertains to the quantity of motion that an object possesses. Any mass that is in motion has momentum. In fact, momentum depends upon mass and velocity, or in other words, the amount of "stuff" that is moving and how fast the "stuff" is moving. A train of roller coaster cars moving at a high speed has a lot of momentum. A tennis ball moving at a high speed has less momentum. And the building you are in, despite its large mass, has no momentum since it is at rest.
WORK (W): A force acting upon an object to cause a movement.
