What is Energy Definition: Energy is the ability to do work. The amount of energy possessed by a body is equal to the amount of work it can do when its energy is released. Thus, energy is defined as the capacity of doing work. Energy is a scalar quantity and it exists in various forms.Units of energy: The units of energy are the same as that of work. In SI system, the … [Read more...] about How to Calculate the Energy Used

How do you find work in physics?
What is the formula for work? Definition: In our daily life "work" implies an activity resulting in muscular or mental exertion. However, in physics the term 'work' is used in a specific sense involves the displacement of a particle or body under the action of a force. "work is said to be done when the point of application of a force moves. Work done in moving a body is equal … [Read more...] about How do you find work in physics?
How do you find Power in Physics
What is Power Figure shows two electric motors, A and B respectively. Each motor lifts an identical load from the floor. Motor A can lift the load more quickly than motor B. Hence, motor A can do the same amount of work in a shorter time. Motor A is said to be more powerful than motor B. Definition: Power is defined as the rate of doing work.In other words, power is … [Read more...] about How do you find Power in Physics
