Potential energy of an electrostatic system in equilibrium - Physics …
2024年12月1日 · So the net force on any charge is ##1/f^2## of what it was at the start. But it was zero at the start, so it is zero at any later time. Therefore, since the force on any charge is always zero, zero work is needed to bring it out to infinity. The initial potential energy of the system is thus zero, as desired.
Potential Energy Transfer from a large mass to accelerate a smaller ...
2024年12月24日 · With the potential energy of a large mass (for example 50 kg at 10 meters high) I want to accelerate a smaller mass (5-25 kg) upwards. I see that simple mechanisms like pulleys, levers, and simple gears leave a lot of kinetic energy in the large mass when it reaches the ground. Is there some...
Change in gravitional potential energy at an angle? - Physics Forums
2008年11月4日 · Change in gravitational potential energy at an angle is directly related to the work done on the object. This is because the work done is equal to the change in energy, and in this case, it is the change in gravitational potential energy. So, the greater the change in gravitational potential energy at an angle, the more work is done on the object.
Gravitational Potential energy on an incline - Physics Forums
2012年4月25日 · potential energy only depends on the height, mgh. whatever the difference in height at the start and end, mg(h2-h1) will be the change in potential energy, either becoming kinetic (rolling down) or becoming potential (going up ramp). the potential has nothing to do with the ramp, only the change in height. g never changes
Net Potential Energy between two Adjacent Ions - Physics Forums
2009年1月13日 · Net potential energy between ions is directly related to lattice energy, which is the energy released when ions come together to form a crystalline lattice. Higher net potential energy between ions results in a higher lattice energy, making the compound more stable and difficult to break apart.
Calculating the conversion of potential energy to thermal - Physics …
2011年9月19日 · What is potential energy and how does it relate to thermal energy? Potential energy is the energy an object possesses due to its position or configuration. When potential energy is converted to thermal energy, it is usually due to a change in the object's position, such as falling or moving from a higher to lower energy state. Can potential ...
Why does electric potential energy increase if you move against …
2024年7月30日 · Electric potential energy is the energy a charged particle possesses due to its position in an electric field. It is a measure of the work done by an external force to move the charge from a reference point (usually at infinity) to its current position within the field.
What is pressure potential energy? - Physics Forums
2012年7月7日 · Pressure potential energy is a type of potential energy, which means it has the potential to be converted into other forms of energy, such as kinetic energy or thermal energy. For example, when a compressed spring is released, the potential energy is converted into kinetic energy as the spring expands.
Deriving Acceleration from Potential Energy? - Physics Forums
2004年8月3日 · Potential energy and acceleration are inversely related. As potential energy increases, acceleration decreases, and vice versa. This is because an object with higher potential energy has less kinetic energy, resulting in a lower acceleration. Can potential energy be negative and still yield acceleration? Yes, potential energy can be negative ...
