1.1.3 Kinetic Energy
Kinetic Energy
infoNote
Kinetic energy is the energy stored in moving objects. Stationary objects have no kinetic energy.
infoNote
FORMULA
- : Kinetic energy (J)
- : Mass (kg)
- : Speed (m/s)
Where m is the mass in kilogrammes, kg, v is the speed, in metres per second, m/s and the kinetic energy, Ek, in joules, J.
