Work-Energy and VRI
The Work/Energy is an interesting one. Losely define, energy is ability to do work. Much like changing Potential Energy to Kinetic Energy and vice versa. This picture from www.physics.upenn.edu describes what work is done with the gravitational force. Most people knows W=Fxd. W is work, F is force (gravitational) and d is distance. Applying force … Read more
Gravitational field and Electric field
To understand the concept of field, it is the best to visualize the field with a diagram. There are the diagrams for both field: The arrows represent the forces expereienced by the subject matter (mass, charges) in 3-D space. Fields are just forces detected in 3-D space around us. Gravitational field is gravitational force at any point … Read more
What is Power?
Power is always confused with Energy which is the ability to do work. In Electrical Calculation, energy = power x time. In other word, power the the rate of energy consumption per unit time. If a lot of energy is consumed in a very short period of time, this is the POWER! A lot of … Read more
