Study Notes
Elastic Potential Energy
- Stored in a bow and arrow when the bow's shape is altered.
- Released when the bow returns to form, converting potential energy into kinetic energy for the arrow's motion.
Roller Coaster Potential Energy
- Cars possess maximal potential energy at the highest point.
- Energy transforms to kinetic as cars descend the hill.
Boulder on a Mountain
- High mass and elevation grant a boulder significant potential energy.
- If the boulder falls, it would release that energy dramatically.
Kinetic Energy in Skateboarding
- A skateboarder transforms potential energy to kinetic as they descend a slope.
Elastic Potential Energy in Rubber Bands
- Stretching a rubber band adds potential energy through shape alteration.
- Upon release, it converts back to kinetic energy.
Gravitational Potential Energy in Swings
- At its peak (point A), potential energy is at maximum, while kinetic energy is minimal.
- At the lowest point (point B), kinetic energy reaches its highest, diminishing potential energy.
Potential Energy in Work
- Gravitational potential energy from a heavy weight converts to kinetic, useful for driving objects (e.g., hammering wood).
Pendulum Energy Conversion
- A swinging pendulum loses potential energy while descending and gains kinetic energy.
- At its lowest point, kinetic energy peaks, allowing it to rise and regain potential energy.
Kinetic to Potential Energy in Tossing a Ball
- Tossing a ball converts kinetic energy into potential as it rises.
- Energy conversion reverses as the ball descends, utilizing potential energy to regain kinetic energy due to gravity.
Potential Energy at Heights
- A person atop a hill possesses potential energy due to mass and elevation, capable of descending.
Parked Bicycle Potential Energy
- A stationary bicycle has potential energy as it can move with applied force.
Car Battery Potential Energy
- A charged car battery stores potential energy, ready for conversion into usable energy.
Gasoline Potential Energy
- Gasoline contains potential energy available for combustion or as chemical energy for vehicle movement.
Flowing River Kinetic Energy
- The movement of water in a river exemplifies kinetic energy, generated by the flow.
