Webb7 apr. 2024 · at a certain height = mgh Gravitational potential energy U = mgh Kinetic energy = 1/2 mass × (velocity)² = 1/2 mv². Work-Energy Theorem. Let u = initial velocity v = final velocity. W = 1/2 mv² – 1/2 mu². Thus work done on a body is equal to increase in Kinetic energy. Physics Formulas For ICSE Class 10 Chapter Machine. 1. WebbChapter 6 - Physics - Google Docs8; ... P Etotal = mgh + 1 2 kx - The full conservation of energy expression will then be - KEi +P Espring,i +P Egrav,i = KEf +P Espring,f +P Egrav,f. When you hold an object, the work done on it is zero. Displacement is zero, so work is zero. However, the muscles deform. ...

Webb8 apr. 2024 · Hint: The dimensions of physical quantities are the powers to which the fundamental quantities are raised to represent that quantity. All physical quantities can be expressed as a combination of seven fundamental or base quantities. Here we have to find the dimensional correctness of the given relation.
