Webmgh = (0.500 kg)(9.80 m/s)(21.00 m) = 4.90 kg⋅m2/s2 = 4.90 J. m g h = ( 0.500 kg) ( 9.80 m/s) ( 21.00 m) = 4.90 kg ⋅ m 2 / s 2 = 4.90 J. Note that the units of gravitational potential energy turn out to be joules, the same as for work and other forms of energy. As the clock runs, the mass is lowered. WebThe equation for change in potential energy states that ΔPE g = mgh. Since h is negative in this case, we will rewrite this as ΔPE g = − mg h to show the minus sign clearly. Thus, −ΔPE g = ΔKE becomes mg h =\frac {1} {2} {mv}^2\\ mg∣h∣ = 21mv2 . Solving for v, we find that mass cancels and that v=\sqrt {2g h }\\ v = 2g∣h∣ . chinese tennis player us open 2019WebFeb 20, 2024 · The work done on the mass is then W = Fd = mgh.
