WebNov 5, 2024 · While inelastic collisions may not conserve total kinetic energy, they do conserve total momentum. A perfectly inelastic collision happens when the maximum amount of kinetic energy in a system is lost. In an inelastic collision the total kinetic energy after the collision is not equal to the total kinetic energy before the collision. WebPotential energy is a property of a system rather than of a single object—due to its physical position. An object’s gravitational potential is due to its position relative to the surroundings within the Earth-object system. The force applied to the object is an external force, from outside the system. When it does positive work it increases ... emory perks
