Energy Calculator: KE and PE
Kinetic and potential energy.
Energy is the capacity to do work.
Kinetic Energy
KE=½mv². Mass times velocity squared, halved.
Potential Energy
PE=mgh. Mass×gravity×height.
Conservation
Total energy is conserved. KE converts to PE and vice versa.
Units
Joules (J). 1 J = 1 kg×m²/s².
Frequently Asked Questions
Kinetic energy?
KE=½mv². Doubling velocity quadruples KE.
Potential energy?
PE=mgh. Higher or heavier=more PE.
Conservation?
Total energy constant. KE↔PE conversion.
