Physics - Work and Energy - When acting (applying force), there is a displacement of the point of application in the direction of the force, is known as work.
5. Both work and heat are measured in Joules. True False 6. A mass of 50 kg is moved vertically upwards through a distance of 2 m. If the gravitational acceleration is 9.8 m s-2, then the work done against gravity is 100 J 980 J 19.6 J 490 J Half-n-half Clue 7. ...
work on it, and transfers no energy to it. (d) Work is done on the briefcase by carrying it up stairs at constant speed, because there is necessarily a component of forceFin the direction of the motion. Energy is transferred to the briefcase and could in turn be used to do work. (...
In physics, energy is defined as the ability to do work. And in physics,work doesn’t refer to what you do at your job. In physics, work meansmoving an object when there is some resistance to its movement. Every timewe lift an object, push it, pull it or carry it, we are doing...
Work done by a person is sometimes called useful work, which is work done on the outside world, such as lifting weights. Useful work requires a force exerted through a distance on the outside world, and so it excludes internal work, such as that done by the heart when pumping blood. ...
WORK = W=Fd Because energy is the capacity to do work , we measure energy and work in the same units (N*m or joules). POWER (P) is the rate of energy generation (or absorption) over time:P = E/t Power's SI unit of measurement is the Watt, representing the generation or absorpt...
