An object's mechanical energy is the sum of the potential and kinetic energy it possesses.
by adding potential energy and kinetic energy, you get mechanical energy.
Because gravitational potential energy is defined by g*m*h where g is the gravitational constant 9.8, m is mass, and h is height. With just height and mass, you cannot calculate "wasted energy" by which i assume you mean energy lost to air resistance. However, if you are given the kinetic energy of the object just before it hits the ground, then you calculate the total energy before falling and compare it to the kinetic energy right before hitting the ground. the difference would represent the energy lost to air resistance
Ofcourse, actually, you have to have mass in order to calculate kinetic energy. Kinetic Energy = 0.5*m*v^2 Where m is the mass. Where v is the velocity. Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
You calculate the new kinetic energy, you calculate the old kinetic energy, then you subtract.
Kinetic Energy = 1/2 Mass * Velocity squared
An object's mechanical energy is the sum of the potential and kinetic energy it possesses.
you have to give it potential energy before it is kinetic
Use the formula for kinetic energy: KE = (1/2)mv2. Replace the numbers you know (mass, and kinetic energy), and solve.
by adding potential energy and kinetic energy, you get mechanical energy.

No, the kinetic energy that was present before the collision will become potential energy.
