Chapter 10, Problem 100A

To determine

To Obtain: Examples of radio, television, print media, and advertisements that illustrate meanings for these terms force, work, power, and energy that differfrom the meaning used in physics. 

Explanation of Solution

Introduction:

In the daily activities of human life, the terms force, work, power, and energy quiet often used somewhere and differ in meaning than that used in physics.

Force: 

In physics, the force is defined as “the product of mass and acceleration” or it is an action used to displace the object/body.

In human daily life, the term force used in various situations. A simple example of a worker who is working in a railway station to carry the goods to the platform. In that situation, the owner of the goods uses the word force. “If it is heavily loaded, he says apply more force to pull it on to the head”.

Work:

In physics, work is defined as “it is the product of force and displacement of an object”.

In general, the regular conversation with friends, one can use the word “have you finished your office work”. 

Another example the apartment watchmen lifting the goods from the ground floor to other floors say the 5th floor, we say he done work. Because he applied a force and move the goods to a required place (through a certain distance).

Power: 

In physics, the rate of doing work is called power.

Obtain the example of work, a watchman moving goods from one place to another place. But if assume the same task is done by two people but one person came early with the same load and another is late. We say that the person who carried early to the destination has more power. Because time is the factor. 

Energy:

In physics, the capacity to do the work is called energy.

In health product advertisements the energy is the word more often used. For example, the company of Boost or Horlicks advertises that “these health drinks provide more energy and one can work/play for long times without strain” that means the capacity to do work increases by drinking such type of drinks. 

Conclusion: 

Various examples can be used for the terms force, work, power, and energy.
