1. Key Concepts and Principles: Physics For Scientists And Engineers With Modern Physics 4th Edition
Physics for scientists and engineers is a fundamental science that deals with the laws of nature and the behavior of matter and energy. The key concepts and principles of physics include:
- Motion: The study of the movement of objects.
- Energy: The ability to do work.
- Momentum: The product of an object’s mass and velocity.
- Force: A push or pull that acts on an object.
- Gravity: The force of attraction between two objects with mass.
2. Classical Mechanics
Laws of Motion
The laws of motion describe the behavior of objects in motion. The three laws of motion are:
- Newton’s first law: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
- Newton’s second law: The acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object.
- Newton’s third law: For every action, there is an equal and opposite reaction.
Energy
Energy is a fundamental concept in physics. Energy can be defined as the ability to do work. There are many different forms of energy, including kinetic energy, potential energy, thermal energy, and electrical energy.
Momentum, Physics for scientists and engineers with modern physics 4th edition
Momentum is a measure of the motion of an object. Momentum is defined as the product of an object’s mass and velocity. Momentum is a conserved quantity, which means that the total momentum of a system remains constant as long as no external forces act on the system.
3. Electromagnetism
Electric Fields
Electric fields are created by electric charges. Electric fields exert a force on electric charges. The electric field around a point charge is given by Coulomb’s law:
F = k
- q1
- q2 / r^2
where F is the force between the charges, k is Coulomb’s constant, q1 and q2 are the charges of the two particles, and r is the distance between the charges.
Magnetic Fields
Magnetic fields are created by moving electric charges. Magnetic fields exert a force on moving electric charges. The magnetic field around a current-carrying wire is given by the Biot-Savart law:
B = (μ0 / 4π)
(I / r)
where B is the magnetic field, μ0 is the permeability of free space, I is the current in the wire, and r is the distance from the wire.
Electromagnetic Waves
Electromagnetic waves are waves that consist of electric and magnetic fields. Electromagnetic waves can travel through space and can be used to transmit information.
