The formula for kinetic energy is K.E. = 1/2 mv^{2}, where "m" stands for mass and "v" stands for velocity. Kinetic energy is typically measured in units of Joules, and 1 Joule is equal to 1 kilogram-meters squared per second squared.
Continue ReadingEnergy is usually divided into two types by chemists. Kinetic energy is the energy that occurs in an object in motion. Examples of kinetic energy include the planets revolving around the sun and a person walking down a street. Potential energy is the energy an object possesses because its position relative to another object. An example of potential energy is a person standing at the top of a staircase.

Full Answer >The formula for efficiency is: efficiency = (useful energy transferred / energy supplied) x 100. It is important to note that the efficiency of any machine or device will always be less than 100 percent.
Full Answer >The average power formula is P = ?E /?t = (Final E - Initial E)/(Final t - Initial t), where "P" is average power, "E" is energy and "t" is time. The average power is equal to the change in energy over the change in time.
Full Answer >The formula for average kinetic energy is one-half the mass times the square of the velocity. Using mathematical notation, the formula can be written as KE_avg = 1/2 x m x v^2, where KE_avg is the average kinetic energy, m is the mass, and v is the velocity.
