potential and kinetic energy units. To convert work into potential energy, you have to act against a particular type of force, and there are several. The force could be gravitation, a spring or an electric field. The characteristics of the force determine the amount of potential energy you ...
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...
and how gravitation, including gravitational potential energy, worked. Kelvin worked out that gravitational contraction, where a large amount of mass shrinks, over time, was likely the mechanism by which the Sun shone. Electromagnetic energy (from, say, electricity) and chemical energy (from, say,...
● Use Einstein’s mass–energy equivalence relationship 𝐸 = 𝑚𝑐 2 to calculate the energy released by processes in which mass is converted to energy, for example: (ACSPH134) production of energy by the sun particle–antiparticle interactions, eg positron–...
Confirmation of the law of universal gravitation Another method to weigh the Sun is to use the law of conservation of energy. This law states that the total energy of an isolated system is constant. In the case of the Sun-Earth system, the total energy is the sum of the kinetic energy...
Conservation of Energy The law of conservation of energy states that energy -- the ability to do work -- can't be created or destroyed. Energy can, however, change forms, which the Newton's Cradle takes advantage of -- particularly the conversion of potential energy to kinetic energy and...
2. If you calculate the cross products AxB and BxA, how will the results compare? They will be exactly the same. They will have the same magnitude, but different directions. They will have different magnitudes, but the same direction. ...
Calculate the answer. 150 = y It is most appropriate to answer word problems with full sentences, so the answer to this problem is best written as: ''The farmer will be able to sell 150 gallons of milk this week.'' Remember that ounces can be abbreviated as ''oz'' and gallons ca...
Usingfunny pick-up linesgives potential partners an idea of your intelligence and humor while showing them that you understand physics well. These lines are clever but not intimidating and can be used to start conversations that may lead to something more! So, give one of these physics-inspired...
if an electron and a proton (both initially at rest and far apart) come together to form a hydrogen atom, 13.6 eV of energy is released (mostly as light). A) By how much does the mass of a H atom differ from the sum of the mass of the electron and proton? Calculate the...
