This spins at high speed on low-friction bearings but most of the time kinetic energy is transferred from other forms of energy only when it is needed. Kinetic energy 12 mv squared. Or E_k frac12 mv 2.
The kinetic energy of a car of mass 1000kg travelling at 10 ms can be calculated as.
Kinetic energy frac12 x mass x speed 2. Q1 A swimmer of mass 70 kg is moving at a speed of 14 ms. The kinetic energy of a car of mass 1000kg travelling at 10 ms can be calculated as. This means that if you double the mass.
