Physics
Kinetic Energy
Calculate energy due to motion.
KE = ½ × m × v²
Formula Explanation
Kinetic energy depends on mass and the square of speed.
Variables Explained
KE = Kinetic energy in joules; m = Mass in kilograms; v = Speed in m/s.
Solved Example
Find the kinetic energy of a 2 kg object moving at 3 m/s.
KE = ½ × 2 × 3² = 9 J.
