Kinetic Energy vs Mass
Kinetic Energy
Kinetic energy is the energy an object possesses due to its motion.
Formula
KE = (1/2) * m * v²
Because velocity is squared, doubling speed quadruples kinetic energy.
Example Calculation
A 70 kg sprinter runs at 10 m/s.
- 01KE = 0.5 * m * v²
- 02KE = 0.5 * 70 * 10²
- 03KE = 0.5 * 70 * 100
- 04KE = 3500 J = 3.5 kJ
