Energy & Work
Watch how energy changes from potential to kinetic as an object falls.
Energy conservation is a fundamental law. It explains why machines can't create energy and why energy transfers are predictable.
If you drop a ball from a height, where does the energy go? Try different heights.
E_{total} = KE + PE = ext{constant}
Use this formula to calculate the relationship between different variables in this concept.
Dropping a 1 kg ball from 10 m gives it 98 J of potential energy, which becomes kinetic energy as it falls.
