An object that is stationary has _____ energy. When the object is pushed, that energy transfers to ____ energy. Throughout this energy transfer, the object's total energy ____.
An object that is stationary has potential energy. When the object is pushed, that energy transfers to kinetic energy. Throughout this energy transfer, the object's total energy remains constant (assuming no other external forces are acting on the object).

When the pendulum shown below swings from point A to point B, what happens to its total mechanical energy (ignoring friction)?
Unfortunately, I cannot analyze or determine the specific details of a pendulum shown below as I am a language model AI. However, in general, as a pendulum swings from point A to point B, its total mechanical energy remains constant if we ignore friction. This is because a pendulum oscillates between potential energy and kinetic energy, with the sum of these energies being constant as long as there are no external forces acting on it.
An object that is stationary has potential energy. When the object is pushed, that energy transfers to kinetic energy. Throughout this energy transfer, the object's total energy remains constant, as energy is conserved.
An object that is stationary has potential energy. When the object is pushed, that energy transfers to kinetic energy. Throughout this energy transfer, the object's total energy remains constant.
To understand this concept, we need to consider the principle of conservation of energy. According to this principle, energy cannot be created or destroyed, but only transferred or converted from one form to another.
1. Potential energy is the energy that an object possesses due to its position or state. For example, a book placed on a shelf has potential energy because of its elevated position relative to the ground. Since the object in question is stationary, it has potential energy.
2. When an external force is applied to the object, doing work on it, the potential energy is transferred to kinetic energy. Kinetic energy is the energy associated with the object's motion. As the object starts moving, its potential energy is gradually converted into kinetic energy, resulting in an increase in kinetic energy.
3. The total energy of the object remains constant throughout this energy transfer. The sum of its potential energy and kinetic energy is constant, assuming that no other external forces, such as friction or air resistance, are acting on the object to dissipate energy. Thus, the increase in kinetic energy is equal to the decrease in potential energy.
In summary, a stationary object has potential energy, which is converted into kinetic energy when it is pushed. Throughout this energy transfer, the object's total energy remains constant due to the principle of conservation of energy.
