Web12 de set. de 2024 · ΔU = − ∫r2r1→F ⋅ d→r = GMEm∫r2r1dr r2 = GMEm( 1 r1 − 1 r2). Since ΔU = U2 − U1 we can adopt a simple expression for U: U = − GMEm r. Note two important items with this definition. First, U → 0 as r → ∞. The potential energy is zero when the two masses are infinitely far apart. WebThe potential energy of an object can be defined as the object's ability to do work and is increased as the object is moved in the opposite direction of the direction of the force. If F represents the conservative force and x the position, the potential energy of the force between the two positions x 1 and x 2 is defined as the negative integral of F from x 1 to … small hand held weed clippers
