Potential

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. In this video lesson we will equate how to gravitational potential energy.

This lesson will show how to set up an equation for the stopping of an electron. The definition of the photoelectric effect will be explained using different examples and diagrams to take a step by step look at the process of setting up equations to gain a better understanding of the concept.

This lesson will look at an example question involving gravity and gravitational acceleration. The given information will assist in solving for the components that need to be found. This lesson will draw diagrams to give a step by step explanation of how to derive the correct equation and better explain the concept.

This lesson will take a look at Newton's Laws of gravitation. An example of how to find the gravitational force between two objects and how to solve. Mrs. Twu will explain how and why gravatational force is usually only looked at when one very heavy object, such as a planet is involved.

Kinetic energy of an object is the energy which it possesses due to its motion. Potential energy is energy stored in a system of forcefully interacting physical entities. Mr. Swords teaches about both kinetic and potential energy.

This lesson will take a look at a projectile fired upward it would reach a maximum height and fall back down, the faster the initial speed the higher the projectile would go, if fired at a fast enough speed the object would keep going and not return with infinite height . This lesson looks at the minimal initial speed provided to an object to never come back is defined as escape speed. An example and diagram will be drawn to explain this concept.

Elastic Potential Energy is potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring.

This lesson will look at an example question involving gravity and circular orbit. The given information will assist in solving for the components that need to be found. This lesson will draw diagrams to give a step by step explanation of how to derive the correct equation and better explain the concept.

This lesson will look at electric force and its similarities to gravitational force in that is is a conservative force will be reviewed. The definition of the changing potential energy will be explained as it relates to electric potential energy. This lesson will give a step by step in-depth explanation of the concept by looking at graphs and diagrams to derive formulas to solve.
