The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula isP.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2at the surface of the earth) and h is the height in meters. H...
and your opinion might change. The safe has potential energy due to the force of gravity, and if someone were to cut the rope holding it, that energy would turn into kinetic energy, and by the time the safe reached you, it would have enough "actualized" energy to give you a splitting...
which is found using the relationship mv2/2, and gravitational potential energy EP, found using the product mgh where g is the acceleration owing to gravity and h is the vertical distance.

Calculate how much will be the increase.A 1.60 m tall person lifts a 1.60 kg book off the ground so it is 2.00 m above the ground. A) What is the potential energy of the book relative to the ground? B) What is the potential energy of the ...
Our equation simplifies to: $$U_i = K_f $$ Substituting in the equation for kinetic energy gives us an expression for the initial gravitational potential energy: $$U_i = 0.5mv_f^2 $$ Step 3: We will calculate the initial height by substituting in the known quantities: $$U_...
How do the 3 laws of moition and law of gravitation relate to the law of conservation of energy and momentum? y=kx, calculate the value of k when y = 12 and x = 8. Determine the potential energy of a 25 kg crate that was dragged 1.0 m up a 30 degree ramp. If the coefficient...
How do I calculate the energy density of either a main-spring (like in a clock) or a motor-spring? Can someone show me values put into the correct formula for something like e.g. steel? I did find some material properties like this: http://www.engineeringtoolbox.com/yo...lus-d_...
Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4. Measure or obtain elsewhere the volume of the substance. Convert the volume to the cubic meter unit. If the volume is given in liter...
Calculate your object's initial potential energy using the following equation: \text{PE}=\text{mass}\times g\times\text{height} Use the height and mass you measured along with 9.8 m/s2as the constant for gravity. The result will be your initial potential energy. ...
