Mechanical energy that has been 'lost' to friction isn't really lost It just is no longer in its mechanical form?
true
When mechanical energy is lost due to friction it becomes?
It is converted into thermal energy, or heat.
When gasoline in a engine some of the chemical energy is transformed into mechanical energy but most of the energy is lost in the form of what?
Heat
According to the law of conservation of mechanical energy if the only force acting on this pendulum is gravity the total energy of the system is .?
Conservation of mechanical energy means that the total mechanical energy doesn't increase or decrease over time.Note that in real systems, some mechanical will always be lost due to friction.
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
Where does the lost energy go?
energy is never lost. It is either converted from one form of energy to another (from heat to mechanical, from mechanical to electric, from electric to heat).

If an object's mechanical energy is equal to potential energy how much kinetic energy does the object have?
Mechanical energy is defined as the SUM of potential energy plus kinetic energy. If all of its mechanical energy is potential energy, it follows that it has no kinetic energy.

Is it conservation of mechanical energy when skydivers drop in the air at a constant rate and why?
No. In free fall, where mechanical energy is conserved, the falling object would go faster and faster. In this case, to fall at a constant speed, mechanical energy is lost, due to friction.
