Newton’s Laws of Motion, Physics 5th edition james s walker
Newton’s three laws of motion are the foundation of classical mechanics. The first law states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
The second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The third law states that for every action, there is an equal and opposite reaction.
Energy and Momentum
Energy is the ability to do work. Momentum is the product of an object’s mass and velocity. The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. The law of conservation of momentum states that the total momentum of a system remains constant as long as no external forces act on the system.
Thermodynamics
Thermodynamics is the study of heat and its relation to other forms of energy. The first law of thermodynamics states that the total energy of a system remains constant. The second law of thermodynamics states that the entropy of a system always increases over time.
