This PowerPoint resource provides a comprehensive and interactive lesson on the concept of elastic potential energy, its calculation, and its relationship to real-world applications. It is ideal for high school physics classes focusing on energy transformations and mechanics.
Key learning objectives:
- Identifying the factors that affect the elastic potential energy stored in a spring, including the spring constant and extension.
- Calculating elastic potential energy using the formula: Elastic Potential Energy (J)=0.5×spring constant (N/m)×(extension (m))2
- Rearranging the formula to solve for spring constant or extension in various scenarios.
Resource features:
The lesson begins with a starter activity comparing the elastic potential energy in stretched springs and reviewing energy equations. Students explore how elastic potential energy relates to energy transformations in systems such as trampolines, slingshots, and bungee cords.
Key topics include:
- The role of the spring constant as a measure of spring stiffness.
- Energy transfer diagrams for systems like bows, arrows, and bungee jumping, illustrating the conversion of elastic potential energy into kinetic and gravitational potential energy.
- Real-world applications, such as springs in suspension systems, toasters, and pens.
Interactive tasks include practice problems calculating elastic potential energy for various springs and analyzing how changing spring constants and extensions affect energy storage. Students also explore conceptual questions about stiffness and force.
