Using Mechanical Energy For Daily Activities: Physics

Mechanical energy is used for many daily activities and can be investigated at different competency levels. At level 3.1, students learn about work, the joule as the SI unit of work, and mechanical energy forms like potential and kinetic energy. They also study the law of conservation of energy and the watt as the power unit. Level 3.2 covers calculating potential and kinetic energy values using equations. Level 3.3 examines simple machines and engines for making work easier through concepts like mechanical advantage, velocity ratio, and efficiency.
