Mechanics
Mechanics, a branch of physics, focuses on the laws of motion, energy, and momentum. These laws govern the behavior of objects in motion and provide a foundation for understanding various phenomena.
Newton’s Laws of Motion
- An object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force.
- The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- For every action, there is an equal and opposite reaction.
Energy and Momentum
- Energy can exist in various forms, such as kinetic energy (energy of motion) and potential energy (energy stored due to position or configuration).
- The total energy of a system remains constant in the absence of external forces.
- Momentum is a measure of an object’s mass and velocity. The total momentum of a system remains constant in the absence of external forces.
Thermodynamics
Thermodynamics, a branch of physics, deals with the study of heat, temperature, and the laws governing energy transfer and conversion.
Laws of Thermodynamics
- The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.
- The second law of thermodynamics states that the entropy of an isolated system can never decrease.
- The third law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero.
Applications of Thermodynamics
