IGCSE PHYSICS - ENERGY, WORK AND POWER (6)

e. = kinetic energy in joules O) = mass in kilograms (kg) = speed in m/s WORKED EXAMPLE An ice skater has a mass of 50 kg and travels at a speed of 5 m/s. Calculate the ice-skater's kinetic energy. rite down the formula: ubstitute the values for m and v: rk out the answer and write down the unit: POTENTIAL ENERGY — îrnv2 k.e. = - 625 J ................
