Resource Description
- Forces that store energy are called non-conservative forces
- Examples – gravity, electric, magnetic, friction, air resistance, tension forces
- Law of conservation of mechanical energy
- Mechanical energy of an object is it’s potential energy + it’s kinetic energy
- Gravitational potential energy = mass x gravity x height
- Kinetic energy = half mass x velocity squared
- Equations for work, energy, potential and kinetic
- Conservation of energy in free fall
- Conservation laws are obeyed by conservative forces , but are broken by non-conservative forces.
