Acceleration of an object is directly pro-
portional to the resultant force, in the
same direction as the force, inversely
proportional to mass.
For every action there is an equal and

work done distance travelled in the direction of mo-

conservation of momentum remains constant given no external re-
sultant force acts on the system.

density mass per unit volume of a material
