Energy stored in your muscles, which ultimately comes from the food you eat.
Muscular (chemical) energy is being converted.
If a body with gravitational potential energy is allowed to fall, then the potential energy is converted (mostly) to kinetic energy.
Gravitational potential energy IS mechanical energy. Mechanical energy includes both kinetic energy, and potential energy.When an object falls, gravitational potential energy will be converted to KINETIC energy.
Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed. Ep = mgh Energy Potential = mass * 9.81 (gravity) * height Speed / Velocity is absent from that equation.
chemical energy
Gravitational potential energy (often abbreviated to GE) which is then converted to kinetic energy when somebody falls.

Not directly; the two are independent. But if an object with gravitational potential energy falls, that energy may be converted to kinetic energy.

chemical energy
The pendulum's momentum or kinetic energy is converted to gravitational potential energy until all of the kinetic energy is converted. The pendulum stops.
Some of its potential energy changes to kinetic energy.

Kinetic energy
If you are standing anywhere where you could fall you have gravitational potential energy. i.e. If you are in a ladder you have potential energy. Irvine ladder breaks and you fall this potential energy is converted to kinetic energy.
The same as when anything falls. Gravitational potential energy is converted to kinetic energy.
If he climbs up the stairs, his potential energy will increase.
