If all the particles in a system have the same velocity, the system is undergoing translational motion and has translational kinetic energy. If an object is rotating, it could have rotational kinetic energy. If it is vibrating, it could have vibrational kinetic energy.
Kinetic energy is a scalar (it has magnitude but no direction); it is always a positive number; and it has SI units of kg · m2/ s2. This new combination of the basic SI units is known as the joule: 1 joule = 1 J = 1. As we will see, the joule is also the unit of work W and potential energy U.
13.2 Kinetic Energy . The first form of energy that we will study is an energy associated with the coherent motion of molecules that constitute a body of mass . m; this energy is called the . kinetic energy (from the Greek word . kinetikos . which translates as . moving). Let us consider a car moving along a straight road (along which we will ...
Kinetic energy is the energy associated with the motion of an object. Work is energy transferred to an object or from an object as the result of the action of an external force. Positive work transfers energy to the object, and negative work transfers energy from the object.
To understand energy and conservation of energy, we must first define some terms: work, kinetic energy (KE), and potential energy (PE). We’ll get to PE in the next Chapter. Let’s look at work and KE. Definition of work done by a force: consider an object moving while a constant force F is applied to the object.
