Chapter 8
Potential energy is not just a property of each object, but also a property of the interactions between objects in a chosen system. For each type of ...
Elastic potential energy is the energy stored as a result of the deformation of an elastic object, such as the stretching of a spring. An object is ...
The mechanical energy E of a system is the sum of its potential energy U and the kinetic energy K of the objects within it. What happens to this ...
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting ...
According to the law of conservation of energy, any transition between kinetic and potential energy conserves the total energy of the system. Hence, the ...
Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from a system as it progresses. Unlike ...
The terms 'conserved quantity' and 'conservation law' have specific scientific meanings in physics, which differ from the ...
When solving problems using the energy conservation law, the object (system) to be studied should first be identified. Often, in applications of energy ...
Force can be calculated from the expression for potential energy, which is a function of position. The component of a conservative force, in a particular ...
Consider a particle moving under the action of a conservative force that has components along each coordinate axis. Each component of force is a function ...
The dynamics of a mechanical system can be easily understood by interpreting a potential energy diagram. Since energy is a scalar quantity, the ...
Energy diagrams are important to understand the dynamics of a system. The topology of an energy diagram helps illustrate the equilibrium points of the ...
