  • Potential energy (video) | Energy | Khan Academy
    Potential energy is the stored energy in an object due to its position, properties, and forces acting on it Common types of potential energy include gravitational, elastic, magnetic, and electric These energies relate to an object's position or shape, and their potential to convert into kinetic energy
  • Kinetic energy (article) | Energy | Khan Academy
    Learn about kinetic energy Use interactive graphs to discover how an object's kinetic energy depends on its mass and speed
  • Kinetic energy (video) | Kinetic energy | Khan Academy
    Any object in motion has the property of kinetic energy Simply put, kinetic energy is motion energy and depends on an object's mass and speed As mass or speed increases, so does kinetic energy
  • Energy | Middle school physics | Science | Khan Academy
    Explore kinetic energy by analyzing how an object’s mass and speed determine its kinetic energy Use interactive graphs to investigate the relationship between kinetic energy, mass, and speed, and interpret data to reveal patterns in how kinetic energy increases with each factor Apply these ideas to real-world scenarios involving moving objects
  • Potential energy (article) | Energy | Khan Academy
    Learn how potential energy is stored in systems of objects that interact through gravitational, electric, or magnetic fields Discover how changing the arrangement of objects in a system affects the system's potential energy
  • Introduction to energy (video) | Khan Academy
    Energy is defined as the ability to do work Energy can be found in many things and can take different forms For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure Energy is never lost, but it can be converted from one form to another
  • Types of energy (article) | Khan Academy
    Here, we’ll look at some types of energy that are particularly important in biological systems, including kinetic energy (the energy of motion), potential energy (energy due to position or structure), and chemical energy (the potential energy of chemical bonds) Energy is never lost, but it can be converted from one of these forms to another
  • High school chemistry (TX TEKS) | Science - Khan Academy
    In this unit, we’ll explain potential and kinetic energy through the invisible motions of particles Then we’ll cover energy transfer and specific heat capacity
  • Gravitational potential energy (article) | Khan Academy
    A weight lifted vertically to acquire gravitational potential energy If the force were to be removed, the object would fall back down to the ground and the gravitational potential energy would be transferred to kinetic energy of the falling object What is interesting about gravitational potential energy is that the zero is chosen arbitrarily
  • Potential energy (video) | Energy | Khan Academy
    Potential energy exists in a system of interacting objects The amount of potential energy depends on the objects' relative positions If two objects attract gravitationally or electrically, potential energy increases as they get farther apart If two objects repel electrically, potential energy increases as they get closer Elastic and chemical potential energy are fundamentally the result of
