gravity
Because a higher ramp gives more potential energy than a shorter one.
The sum of potential and kinetic energy gives you the Mechanical Energy of the system
gravity
chemical potential energy
Potential energy
nopes for our cars need kinetic energy
Elastic cars work by converting elastic potential energy into kinetic energy. The most potential energy, the more kinetic energy.
Combustion converts chemical energy (potential energy) into mechanical energy (kinetic energy).
With potential energy, what matters is the difference in potential energy, not the energy in absolute terms. To simplify calculations, the gravitational potential at infinity is arbitrarily set to zero. This gives objects that are nearer than infinity (to any object that attracts them gravitationally), a negative potential energy.With potential energy, what matters is the difference in potential energy, not the energy in absolute terms.
