Action Potentials An action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. An action potential occurs when a neuron sends information down an axon‚ away from the cell body. A threshold is the minimum amount of stimulation needed to start a neural impulse (you know‚ the electrical impulses that travel throughout your body carrying important information). Action potentials generated by neural impulses are

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters
