Potential Energy Concept The force on an object is the negative of the derivative of the potential function U This means it is the negative of the slope of the potential energy curve Plots of potential functions are valuable aids to visualizing the change ofGravitational potential energy is one type of potential energy and is equal to the product of the object's mass (m), the acceleration caused by gravity (g), and the object's height (h) as distance from the surface of the ground (the body) In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth's gravity would have 147 Formula (i) W = PE = mgh Solution W = mgh = x (98) x 10 = 1960J The work done to take an object of mass kg to a height of 10 m is 1960 J Question 7 A body of 05 kg thrown upwards reaches a maximum height of 5 m Calculate the work done by the force of gravity during this vertical displacement

We can derive the technical formula of the pump motor according to the principle of energy conservation The effective work done by the pump is W=Mgh (send a certain weight of medium to a certain height h, h is the lift) M is the mass of water m = ρV (ρ is the density of the medium, the volume of the V medium) V = Qt (Q represents the flowW = mgh Where, W = work done g = acceleration due to gravity h = height of free fall If the angle between gravitational force and direction of motion is 𝚹, then work done due to gravity is given by W = mgh cos 𝚹 So if an object is moving in horizontal direction on the surface of earth, then work done by gravity is 'zero'The magnitude of the falling body depends on the mass, gravitational constant and height from which it is falling The work done by gravity is given by the formula, Wg = mg (∆ h) Where, m = mass, g = gravity, h= height
