• Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. • Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy. • Thermal energy cannot do work, but mechanical energy can do work. Since friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s

First the principle of the Conservation of Mechanical Energy was stated:. The total mechanical energy (defined as the sum of its potential and kinetic energies) of a particle being acted on by only conservative forces is constant.. An isolated system is one in which no external force causes energy changes. If only conservative forces act on an object and. The kinetic energy formula is expressed as: where m is the mass of the body moving with velocity v. if the mass is given in kilogram and velocity v is given in meter/second then kinetic energy comes out in joules. one joule is the energy when a force of one newton displaces a body through one meter The formula for Hooke's law specifically relates the change in extension of the spring, x , to the restoring force, F , generated in it: F = − k x. F = −kx F = −kx. The extra term, k , is the spring constant. The value of this constant depends on the qualities of the specific spring, and this can be directly derived from the properties.

Potential and Kinetic Energy Energy. Energy is the capacity to do work.. The unit of energy is J (Joule) which is also kg m 2 /s 2 (kilogram meter squared per second squared). Energy can be in many forms! Here we look at Potential Energy (PE) and Kinetic Energy (KE) Write down the formula. So to get the GPE of an object you need a formula, the formula is MASS X GRAVITY X HEIGHT (M X G X H). Put the data in the formula.
