Ch 13.4 - PPT - Conservation of Energy
... – Whenever the total energy in a system increases, it must be due to energy that enters the system from an external source. • Thermodynamics describes energy conservation. – For any system, the net change in energy equals the energy transferred as work and as heat. – This form of the law of energy c ...

... Reflect: Fon spring is always the force applied to one end of the spring, thus we did not need to double the 15.0 N force. Consider a free-body diagram of a spring at rest; forces of equal magnitude and opposite direction are always applied to both ends of every section of the spring examined. 7.31. ...

Potential Energy - The Lesson Builder
... This statement is true for all conservative systems, and thus for all systems in which U is defined. With this equation we have completed our proof of the conservation of mechanical energy within conservative systems. The relation between U, K and E is elegantly simple, and is derived from our conce ...

Gravity and Potential Energy
... Not all of the energy in the roller coaster system is conserved in a non-idealized system. This is because of nonconservative forces. Friction is the main cause of energy leaks in the system and the reason why mechanical energy is not fully conserved. The friction between the train and it’s tracks a ...

Conservation of Energy Energy can be in many different forms
... When a rubber band is stretched, kinetic energy is transformed into potential energy. When a stretched rubber band is released its potential energy is transformed into kinetic energy as the rubber band moves. When a book is lifted to a shelf, kinetic energy is transformed into potential energy. ...

Work-Energy Theorem
... Suppose the player in your game must push a secret stone wall at least 2m to gain access to a bonus level. If the player’s character can push with a horizontal force of 1500N and kinetic frictional force of 50N is working against him, how much work total will it take to move the wall out of the way? ...
