Mechanical work, heating, electrical work, radiation
Force moves an object through a distance
Energy transferred from hotter to colder object
Energy cannot be created or destroyed, only transferred, stored, or dissipated
No energy can enter or leave
Maximum gravitational potential energy (GPE)
Maximum kinetic energy (KE)
Energy transferred to thermal, becomes less useful
Use lubricant (e.g., oil on fixed point)
All gravitational potential energy (GPE)
Kinetic energy (KE) is at maximum
KE zero, all energy is elastic potential energy (EPE)
Energy transferred from one store to another
Work (J)=Force (N)×Distance (m)\text{Work (J)} = \text{Force (N)} \times \text{Distance (m)}Work (J)=Force (N)×Distance (m)
Kinetic energy → thermal energy in brakes (friction)
