WebHope this helps. To prove that Kinetic Energy is ½ mv^2. We already know that Energy w = f x s that is force x displacement. So, ΔK = W = FΔs = maΔs. From the third equation … The megajoule is approximately the kinetic energy of a one megagram (tonne) vehicle moving at 161 km/h (100 mph). The energy required to heat 10 L of liquid water at constant pressure from 0 °C (32 °F) to 100 °C (212 °F) is approximately 4.2 MJ. One kilowatt-hour of electricity is 3.6 megajoules. Gigajoule Meer weergeven The joule is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force … Meer weergeven The cgs system had been declared official in 1881, at the first International Electrical Congress.
