# Potential energy diagram

Power An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. B Current is directly proportional to the voltage. A fourfold increase in the voltage would cause a fourfold increase in the current. A circuit is wired with a power supply, a resistor and an ammeter for measuring current. The ammeter reads a current of 24 mA milliAmps.

Determine the new current if the voltage of the power supply was See Answer A circuit is wired with a power supply, a resistor and an ammeter for measuring current.

But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current. These two factors offset each other and there is no overall change in the current.

But current is also inversely proportional to the resistance; a halving of the resistance will double the current. So the new current can be found by tripling and then doubling the old current of 24 mA.

So the new current can be found by halving and then halving again the old current of 24 mA. Use the Ohm's law equation to provide numerical answers to the following questions: An electrical device with a resistance of 3. When a voltage of V is impressed across an electric heater, a current of Graph 1: Use the potential energy diagram for the reaction X + Y -> Z to complete the chart below.

Which letter indicates the potential energy of the activated complex? __c____ 3. Which letter indicates the potential. Explore the interactions between various combinations of two atoms. Observe the the total force acting on the atoms or the individual attractive and repulsive forces. Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction.

The energy changes that occur during a chemical reaction can be shown in a diagram called a potential energy diagram, or sometimes called a reaction progress curve. A potential energy diagram shows the change in potential energy of a system as reactants are converted into products.

Potential energy diagrams Consider an arbitrary potential energy shown schematically below. There are a number of important qualitative features of the behavior of the system that can be. Potential energy is energy stored in a system of forcefully interacting physical entities.. he SI unit for measuring work and energy is the joule (J).. The term potential energy was introduced by the 19th century Scottish engineer and physicist William Rankine.
