Pendulum Flashcards
The law of conservation of energy
Energy can be transferred usefully stored or dissipated but it cannot be created or destroyed
What is a system
A system is an object or group of objects
What is a close system
No energy can leave or enter
Describe the energy changes in a pendulum from right to left ( if it was swinging)
Maximum gravitational potential energy of the mass
Gravitational potential energy converted to kinetic energy
Maximum kinetic energy of the mass
Kinetic energy transferred to gravitational potential energy
Maximum gravitational potential energy of the mass
What does friction caused
Energy transferred to thermal energy store
Another word for waste energy
Dissapate
How can you reduce unwanted energy transfers
Reduce friction
How to reduce energy transferred in pendulum
Lubricant on fixed point
Remove air particles
