In summary, the conversation discusses the calculation of potential and potential difference between two points due to an electric charge, as well as the change in electric potential energy and the work done by the electric field. The solutions provided involve using the formula VA=kq/r and ...
Calculating Work Done How to Calculate Work Done by a Variable Force Lesson Summary What is Work? In life, when a person participates in an activity or performs a job, it is thought of as doing work. The greater the energy needed to do the activity, the more it is thought of as doing...
All forms of energy are either kinetic or potential. The energy in motion is known as Kinetic Energy, whereas Potential Energy is the energy stored in an object and is measured by the amount of work done. Types of Energy Some other types of energy are given below: Mechanical energy Mechanic...
1. An example of Kinetic Energy would be: a) a moving car b) a stretched rubber band that was just released c) a charge particle in an electric field d) all of the above 2. An example of Potential Energy would be: a) a moving car ...
Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to themotionof the object, the work is considered to be negative, implying that energy is taken from the object. The units in wh...
Types of Energy Some common forms of energy include the kinetic energy, it is of a moving object. The potential energy is stored by an object’s position in a force field. It can be gravitational, electric or magnetic. The elastic energy is stored by stretching solid objects. The chemical...
cannot store the potential energy in its lattice due to its rigid structure and it can only possess kinetic energy. The work done by any force acting on a rigid body is eventually equal to the change in its kinetic energy and it is the basis of the work-energy equation for rigid bodies...
