Change in kinetic energy refers to the difference between the initial and final kinetic energies of an object as it undergoes a change in velocity. The formula to calculate the change in kinetic energy () is given by:
Where:
- = Change in kinetic energy in (J)
- = Mass of the object in (kg)
- = Final velocity of the object in (m/s)^ 2
- = Initial velocity of the object in (m/s)^ 2
The SI unit of kinetic energy is joules (J).
