Sep 04, · (v) Work done by the force of gravity on a particle of mass m is given by W = mgh where, g is acceleration due to gravity and h is height through which the particle is displaced (vi) Work done in compressing or stretching a spring is given by W = \(\frac{1}{2}\)kx² where, k is spring constant and x is displacement from mean positionNov 19, 09 · In physics, for the formula w=mgh, is mass in kilograms, and height in metres?Molar mass (M) is equal to the mass of one mole of a particular element or compound;
Work has units of Joules (J) Remember work is defined as F * d cos(θ), which has units of N * m, W = mgh The work done by gravity while the object moves to h/2 is mg(h/2) The work done while the object is moving from h/2 to h is also mg(h/2) Work is negative in this case, because gravity works against the object being movedStart studying Physics Chapter 4 Work and Energy Learn vocabulary, terms, and more with flashcards, games, and other study toolsPE = mgh Calculate GPE for different gravity of different enviornments Earth, the Moon, Jupiter, or specify your own Free online physics calculators, mechanics, energy, calculators
The watt (symbol W) is a unit of power or radiant fluxIn the International System of Units (SI), it is defined as a derived unit of (in SI base units) 1 kg⋅m 2 ⋅s −3 or, equivalently, 1 joule per secondIt is used to quantify the rate of energy transferThe watt is named after James Watt, an 18thcentury Scottish inventorCalculate the unknown variable in the equation for gravitational potential energy, where potential energy is equal to mass multiplied by gravity and height;By lifting the book at a constant velocity, a FBD shows that the external force = mg, which gives W = mgh when raised to a height, h But, the gravitational field also does internal work on the book and it's negative as the book moves up and the gravitational force is down
