Potential Energy
Stored energy due to an object's position.
Elastic Potential Energy
Energy stored in materials when stretched or compressed.
Hooke's Law
Describes relationship between force and spring displacement.
Equilibrium Position
Natural position of a spring with no force applied.
Zero-Potential Energy Position
Position where potential energy is zero.
Kinetic Energy
Energy of an object in motion.
Mechanical Energy
Energy due to motion or position of an object.
Conserved Quantity
Quantity that remains constant without external forces.
Work
Energy transfer that causes displacement of an object.
Power
Rate of doing work over time.
Stretch
Deformation of elastic materials increasing potential energy.
Compression
Reduction in volume of elastic materials storing energy.
Bungee Cord
Elastic material that stores energy when stretched.
Trampoline
Device that stores elastic potential energy when compressed.
Spring Constant
Measure of a spring's stiffness in Hooke's Law.
Energy Conversion
Transformation of potential energy to kinetic energy.
Gravitational Potential Energy
Potential energy due to an object's height above ground.
Displacement
Distance moved in a specific direction.
Average Passenger Work
Work needed to elevate one average passenger.
Total Work
Work calculated for multiple objects or passengers.
Energy Relationship
Kinetic energy increases with the square of speed.
Force Application
Mechanical energy enables force to cause displacement.
