FAQs on Thermal energy from friction Video Lecture - Crash Course for PAT
| 1. What is work? |  |
Ans. Work is defined as the transfer of energy that occurs when an object is moved against an opposing force. It is calculated by multiplying the force applied to an object by the distance over which the force is applied in the direction of the force.
| 2. How is work related to energy? | |
Ans. Work and energy are closely related concepts. When work is done on an object, energy is transferred to that object, causing a change in its energy state. Similarly, when work is done by an object, it loses energy. Therefore, work and energy are interconnected and can be used to describe the transfer and transformation of energy in a system.
| 3. What is the unit of work? | |
Ans. The unit of work is the joule (J). A joule is equivalent to the work done when a force of one newton is applied over a distance of one meter in the direction of the force. In some cases, other units such as kilojoules (kJ) or foot-pounds (ft-lb) may also be used to express work.
| 4. What is the principle of conservation of energy? | |
Ans. The principle of conservation of energy states that energy cannot be created or destroyed, but it can only be transferred or transformed from one form to another. In other words, the total energy of a closed system remains constant over time. This principle is applicable to various energy forms, including mechanical, thermal, chemical, and electrical energy.
| 5. How is the concept of work and energy applied in real-life situations? | |
Ans. The concept of work and energy is applied in various real-life situations. For example, it helps in understanding the efficiency of machines, calculating the amount of energy required for certain tasks, designing energy-efficient buildings, and analyzing the performance of vehicles. Work and energy concepts are also used in fields such as physics, engineering, and environmental science to solve practical problems and optimize energy usage.
