What is the law of universal gravitation?
Objects in motion tend to stay in motion unless acted upon by an external force.
The force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The rate of change of momentum of an object is directly proportional to the force applied and occurs in the direction of the force.
The pressure applied to a fluid is transmitted undiminished throughout the fluid in all directions.

It is hyperbolic
#12
What is the principle of conservation of mechanical energy?
Mechanical energy cannot be created nor destroyed, only transferred or transformed.
The rate of change of momentum of an object is directly proportional to the force applied and occurs in the direction of the force.
The pressure applied to a fluid is transmitted undiminished throughout the fluid in all directions.
For every action, there is an equal and opposite reaction.
#13
