Kinetic and Potential Energy > Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: [math]K.E. = 0.5 m * v^2[/math]. read more
To calculate kinetic energy, write out a formula where kinetic energy is equal to 0.5 times mass times velocity squared. Add in the value for the mass of the object, then the velocity with which it is moving. Solve for the unknown variable. Your answer should be stated in joules, or J. read more
