Mgh unit physics
Webbf = w = m g. The work we do on the rock equals the force we exert multiplied by the distance, d, that we lift the rock. The work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. Webb9 apr. 2024 · Energy density is defined as the energy stored per unit volume. Thus mathematically, Energy Density = Energy/Volume. And, Energy=Force×displacement. Energy=ma×d. Where m=mass,a=acceleration and d=displacement. Thus,dimensions formula of energy = M1L2T−2. Dimension formula of Volume = M0L3T0.
