Key Teachings:

Newton's Laws:

First Law - Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Second Law - The relationship between an object's mass m, its acceleration a, and the applied force F is F =ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

Third Law - For every action there is an equal and opposite reaction.

Law of Energy Conservation:

The law of conservation of Energy states that in a closed system, energy is always conserved. A closed system is one in which no energy crosses the boundary of the system.

 

Law of Momentum Conservation:

The total momentum before the interaction will equal the total momentum after the interaction
