W = m×g×h = mgh Above is the potential energy formula. As per thelaw of conservation of energy, since the work done on the object is equal to m×g×h, the energy gained by the object = m×g×h, which in this case is the potential energy E. ...
Coming back to Newton’s Cradle, at rest, the balls have zero potential energy, as they can’t move down any further (Potential Energy = mgh, at rest h = 0) and zero kinetic energy, since they aren’t moving (Kinetic Energy = 1/2 mv2, at rest v = 0). Similarly, the balls d...
If it does get banned, I mean, the obvious thing is we're looking at a huge shift of advertising dollars out of the platform that've got to go somewhere else. I think in the US, it's over $10 billion in ad revenues this year, 2024. So I mean, that's...
but states have been passing laws legalizing these products. This has in turn led to a patchwork of laws that have varied impact on guaranteeing that consumers get what they expect. Cannabidiol (CBD) does not come under FDA regulation. ...
Does mass equal gravitational weight? Is the gravitational force exerted on an object by Earth? How does the force of gravity depend on the mass of two objects? What is the difference between gravitational force and magnetic force? Which of these is the universal gravitational...
Does it really mean "90-degrees"? How do we construct the observer's x-axis (her "spaceline") given her t-axis (her "timeline"), starting from a "circle" (which is what defines orthogonality)? Is relativity really "so unlike anything we have ever seen" or can it be...
We will derive Bernoulli's equation by setting the energy gained by the fluid equal to the external work done on the fluid. [Is Bernoulli's equation different from Bernoulli's principle?] Let's assume the energy system we're considering is composed of the volumes of water 1 and 2 as...
How much does 1 ton equal to in kg? From the expression E = mgh for potential energy, how can I express the unit of energy, the joule, in terms of kilograms, meters and seconds? (a) Calculate the energy released by the total ...
tomato, soybean, rice, and spinach. [2] The problem with trying to increase GABA in your diet is that the amount of GABA in supplements is much higher than in food. For example, to get a dose equal to 100 milligrams of supplement, you would need to eat about five pounds of spinach....
If you hold one mass in place, then that restraining force does no work, so all the GPE goes into the KE of the second mass. You can calculate the work done more easily (as only one mass is moving) by integrating the force. This does indeed equal the usual formula for potential ...
