I haven't used half of the information give in the problem and I'm pretty sure potential energy is not neccissarly the same as work done. Also if the was the case wouldn't the spring constant reach it's ultimate tensile stress or fracture point. Please help I was away when we ...

. In fact, theamount of potential energy a system possesses is equal to the work done on the system. Potential energy also can be transformed into other forms of energy. For example, when a ball is held above the ground and released, the potential energy is transformed into kinetic energy...
Physics 1D03 - Lecture 22 Potential Energy Work and potential energy Conservative and non-conservative forces Gravitational and elastic potential energy. Conservative Forces: The forces is conservative if the work done by it on a particle that moves between two points depends only on these points an...
Could I say that the total energy of a system is the sum of the work of all force + kinetic energy ? I'm always confuse on which force gives a potential or not... But maybe at the end, it's just the sum of work of each force ? newtonian-mechanics forces energy work potential-...
1.6.Does the potential energy increase or decrease? 1.7. How much work is done by the electric field due to chargeQ as q moves fromA toB?2. The attempt at a solution 1.1 VA=kq/r =(9x109)(10n)/0.3 =300V You substituted wrong value for the charge - everywhere. The sign of the...
More energy is used, which means more work is done. That work takes more power, which generates more heat. The potential energy of any given object is a measurement of its potential to do work, create heat and generate power. For this reason, the calculation of an object's potential ...
True or False?Work-Energy Principle:When work is done by many forces acting on a body, the kinetic energy of the object changes. The total work done by all the forces appears as change in kinetic energy of the object, which is the statement o...
